- 3 tablespoons chili powder
- 1 tablespoon cumin
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 3 ½ cups water or vegetable broth

Instructions

- Cover and cook on high for 2½ to 3 hours, or on low for 5 to 6 hours.

The filling should become tender and thick as it simmers slowly, developing a rich, hearty flavor.
- Once the lentils are fully cooked and the mixture has thickened, spoon the filling into taco shells or warm tortillas. Add your favorite toppings such as avocado, shredded lettuce, diced tomatoes, salsa, or a sprinkle of cheese, and serve immediately.
