French onion soup and black bean soup are also pretty easy, and vegan versions can be just as good as meat-stock based versions. I think I'd have to make them and write it down as I go though just to be sure I got it right, but the French Onion soup is dead-easy, something like:
4-6 yellow/spanish/sweet onions, sliced (I prefer the onions that weigh less; less moisture, more flavor).
2-3 tbsp vegetable oil
1.5 qt vegetable broth (homemade or store bought are both fine)
1 sprig fresh thyme
3 tbsp all purpose flour
1. In a large stock pot, over medium-low heat, add oil and sliced onions, toss to coat, cover and sweat onions for about 10 minutes (they should be kinda soft and wilty).
2. Uncover, raise heat to medium, and saute onions stirring regularly (for a long ass time) until onions are a a nicely carmelized brown color. Usually about 45 minutes. As you go, caramelized bits might stick to the pot. Use a wooden spoon/spatula to scrape the bits off the bottom of the pot so they don't burn. (You really do need to stir regularly this whole time, and it's more a color thing than a time thing; you're after a deep caramel, medium brown color).
3. Add the flour. Shit might seize up a little, but it's no biggie. Continue to cook & stir for about 5 minutes or so, until the floury onions are about the same color brown they were before you added the flour.
4. Add the vegetable broth. Simmer partially covered for at least 30 minutes.
5. Use your fingers to strip the herby bits off the thyme sprig and drop them in (don't throw the whole sprig in, unless you want to I guess). Salt to taste, if necessary.
6. Options:
a) add a few tbsp of sherry and simmer for another 10m.
b) In the serving bowls, float a bit of toast/crouton with a slice of good swiss cheese on top, then broil to melt/caramelize the cheese a bit. (yeah, no longer vegan at this point). Gruyere works well too, but changes the flavor a lot, so only use it if you like Gruyere.
c) You can use beef stock, or even chicken stock if you prefer, but I like veggie broth better.
d) Technically, even the thyme is optional, but it brings a great flavor.
I also have a pretty solid Minestrone recipe. I could post it up when I get home if anyone is interested.
