Here is a very simple recipe I use,
1-3 T Canola or Olive Oil
2-3 cloves Garlic, minced
1 bunch of Green Onions,minced
1 bunch of Cilantro, chopped
8 cups of cooked Black Beans
8 Concassed Tomatoes, chopped
8 cups of Chicken or Vegetable Stock
2 t Oregano or 2 T Fresh Oregano
Crushed Red Peppers
Salt & Pepper to taste
Place 1-2 T of oil in a pot(Add more if you need it), Add the garlic, green onions and Cilantro. Sautee at Medium High heat until sweated, but not brown. Add the Black beans, tomatoes and cook for about 4 minutes. Then add the stock and seasonings and bring it down to a simmer. Cook for about 1 hour, longer if you like it thicker. I usually serve it with a dollop of sour cream and a spoonful of hot salsa on top of the cream. A nice cheddar cheese to sprinkle on top is also a must.
