For an extra layer of flavor, sauté 1/2 cup of finely diced onion and 2 cloves of minced garlic in a tablespoon of olive oil before adding the beans and water. A dash of hot sauce or a sprinkle of chopped cilantro adds a delightful finishing touch. Feel free to experiment with different types of beans, such as black beans or pinto beans, to create your own unique variation. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave.
