Since you're a nutritionist, making food for people would be awesome.

I'm sorry to hear that, eric.

I saw a girl who posted a handmade sign at a coffee shop.
It said something like,

I will COOK for you.
Your kitchen, your ingredients, my spice!

That might make things easier since you don't have a way to transport lots of food for catering. But then you could end up with meaty ingredients.

One thing you will need to check into is getting your kitchen certified (if you cook there to sell stuff). Otherwise, you can get fined. Home kitchens can be certified, but they have to meet certain criteria.

There's a place here (on a campus) that has a HUGE certified kitchen and people can rent out the space to sell things they cook/bake. ITs pretty cheap. Maybe there is a resource like that. Or you could ask your local veg restaurant if you could use their space after hours.

I also know a woman who looks after old people and takes them out shopping and running errands. I don't know if this interests you, but old people always need help doing things.

I've been teaching mini art lessons at the farmers market, so that's how I'm supplementing. One week I only made $9  ::)
Its not a ton of money (I usually make $20 or so in 3 hours) but I'm networking and getting people interested in my other art classes.
:P

in the various spas and salons I have worked at, people would come in at various times selling sandwiches, soups, desserts, bread, etc.  Alot of us were/are too busy to go out or forget to bring our lunch, and would be excited to see them!  We have a sandwich guy that comes 3 times a week and the bread lady comes every thursday.  sometimes we even make request and they have made special stuff for us. 

hairstylist are always in a hurry, eating on the go, they relied on people to bring them stuff.  we got to the point that we would call them if they missed a day. You might try baking a free batch of cookies(or anything), take it in with your cards, and tell the receptionist a little about what you could make.  Start out on a slow day(early in the week), maybe in the afternoon, when we are usually hungry and tired. I bet you would do really well

I make my own wine, and that helps me not to buy wine that I haven't made. it sucks having to wait 6 months to a year before you can drink it. Solution? Make beer or hard lemonade in the meantime. It's drinkable within about a month, and doesn't require many extra components of winemaking.

Would you suggest any home brew kits?  Brewing my own beer is one of those holy grails in my life and it's really about time I get started on this whole process.

I've never actually brewed my own beer, so I can't comment but check your local brewshop and ask them about the beer kits they have available. I think it's usually a matter of what you're really looking to make. The equipment will probably cost you around $100-$150 initially, plus the price of grains and hops. But after that, you only have to ever buy more grains and hops to make more beer. You can check some brew forums (I like homebrewtalk). A lot of people post recipes for successful and delicious beers they've made. And for wine (I post on the winepress.us forums), you can find some good, easy recipes for making wine from grape concentrates, apple juice, even fruit preserves! The sky is the limit. And it's a lot of fun!

It's awesome that you posted this, hesp. I have been thinking about doing the own thing with my cooking. My vegan roommate doesn't cook a lot and when I told her about my idea she said that she'd buy my food! so we set up an arrangement in which she pays for the ingredients, I cook, and we share the food. So basically I get to eat a lot for free. But I would like to take that a step further and try to make it profitable on a slightly larger scale.  Some people have suggested selling my baked goods on etsy, others have suggested setting up my own website for people to order them from. Basically my biggest issue would be transporting the food I made to people, so just shipping baked goods makes it a little simpler perhaps.  But I don't know, it's still kind of a big question mark. 
I like lubi's sandwich selling thing. I could try something like that maybe? Anyway, I look forward to seeing other people's ideas.  This was a great thing to bring up. Thanks, hesp :)

With the recent downturn in the automotive industy and many people taking between 5% and 25% pay cuts this year quite a few people where I work have come up with some money making ideas to help them out financially. One guy got a paper round and I think that pays a lot better than the paper round I had as a kid using my bike. I think he told me he got about $800 a month and you can claim car expenses on your taxes too.

We also have some employees who have a ready made meals service. They have a menu you can choose from and need to hand in on Friday and they bring in your order on Monday. It's all very professionally handled with returnable deposits for tuppaware. Being as most of our hourly assocites are hispanic the food choices are greaed to them, but it seems to be pretty popular.

Dog sitting is a good way to make money, we pay $50 a night when we go away and have someone take care of our crew, we have a vet-tech doing this for us know which is good as they can pill the cat! But I think $50 a day to stay in a nice house and eat my food and drink my beer is an easy way to make money.

Having to pay for health insurance here soon is going to a bummer, any chance of getting job with health benefits?

I had a nightmare about the KGB because of Cap's post!  ;D

P and I have both thought about dog walking several times, but it seems like you should have special insurance, and stuff. It always seemed scary. I've thought about doing a lot of these things.
