Some recipes for beans and rice involve overnight bean-soaking, 10 kinds of spices and lots of simmering and stirring. But it doesn't have to be that way -- you can prepare a pot in a matter of minutes using ingredients you probably already have on hand. Sauté some garlic, bell peppers and onions, then throw in a can each of tomatoes and beans (rinse the beans first to cut down on sodium), a dash of oregano and some hot sauce or cayenne pepper. Simmer for a few minutes and serve with cooked rice. If you've got any leftover chicken, sausage or shrimp, just add it to the bean mixture in the last few minutes of cooking so it heats through.
