This recipe is REALLY easy. I don't exactly measure it out.
Heat up a frying pan, add sliced onion and fry until brown, DICE the tofu and fry up until all the sides are golden and crispy. (This can sometimes take a while depending on the brand of tofu, I'm in Australia and I just get a sort of squishy one in a carton..It takes longer than the super firm stuff).
While you're doing this, steam some pumpkin (I use the microwave but if you don't have one just steam it normally I suppose). When the pumpkin is really soft and gooey but still holding its shape, toss it into the frying pan with the onion and tofu. I went on a special mission to an American grocery store to get liquid smoke, and I find that mixing liquid smoke with soy sauce adds a bit of extra flavour. Its fine without it, howe'ver. Splash on as much of the sauce as you like and enjoy!!!
I really like it when I'm hungover for some reason. Adding a handful of baby spinach leaves is a nice addition as well.
