Step 2) Heat 1/4 cup oil in the same saucepan over medium-high heat. Add onions and peppers; sauté for 2 to 3 minutes or until softened. Stir in garlic, oregano and drained beans. Reduce heat and continue cooking for 2 minutes. Add water and 3 teaspoons bouillon powder; pour over the beans and bring to a gentle boil over medium heat. Add bay leaf and epazote, if desired. Cook, stirring occasionally for 1 hour or until beans are tender. Remove bay leaf, stir in cilantro and served immediately over cooked rice.
