As a vegetarian I eat a lot of beans. They are filling, inexpensive, delicious when properly cooked, and can be combined with many other foods. My favourites for Mexican-style foods are pinto and black beans. I usually cook them from dry, but try to have some plain canned beans available for last-minute meals. For tacos or burritos you could also buy the canned re-fried beans, but they are expensive depending on your location. I think my recipe is much tastier, and certainly cheaper. Here’s how I make my Mexican-style beans: Fry chopped onions in oil. Add garlic, ground cumin and coriander.
