Rice and beans is a classic dish that is popular in many cultures around the world. Cook some rice and set it aside. In a separate pan, sauté some onions, garlic, and bell peppers until tender. Add a can of black beans (or any other type of beans you prefer) and cook until heated through. Season with cumin, chili powder, and salt to taste. Serve the beans over the rice and garnish with chopped cilantro.
