Spread and enjoy!
This is one of a number of things I've discovered that help me survive as a broke, busy, vegetarian grad student. Sometimes when I'm less busy I'll up the preparation time to 5 minutes by throwing the vegan bread in the toaster first. This is nice because the heat from the toast warms up the beans a bit; I get a warm lunch without worrying about cooking or even using a microwave.
I'm vegetarian rather than vegan and I haven't been able to convince myself to give up cheese yet, so I occasionally add a slice or two of cheddar to this recipe. It works just fine without it, though.
I may begin a little series here on dorm-room vegan food; stuff I have learned to make in a hurry with only a hotpot, an electric wok, and a toaster oven. I hate that durn communal kitchen; its not kept clean.
