My friend Sunee copied this black bean recipe from America's Test Kitchen cook book for me, but I found this recipe from allrecipes.com that's very similar, if you subtract the carrots and corn. The original recipe doesn't call for it, but I added a finely diced carrot to the onions and jalapeno. You can't really taste the flavor of the cooked carrot, but it makes the soup even more nutritious.
And I can't say enough about this corn meal. It's from close to here, and I've been using it since I started cooking about five years ago. The recipe is on the back of the package of corn meal.
This is one of the cheapest and most delicious meals I know how to make. Do you have any cheap and wholesome meals you rely on?
