1-Preheat the oven to 375°F and grease a 9×13-inch casserole dish.

2-In a large skillet over medium-high heat, brown 1.5 pounds of ground beef for 5-6 minutes until mostly cooked.

3-Add 1 medium chopped yellow onion and 3 finely chopped garlic cloves, cooking for about 5 minutes until softened and fragrant.

4-Stir in 1 envelope of taco seasoning, ¾ cup water, 1 can (15.5 oz) drained and rinsed black beans, 1 can (14.5 oz) diced tomatoes, 1 can (4 oz) diced green chiles, ½ teaspoon salt, and ½ teaspoon ground black pepper. Simmer on medium-low for 5 minutes until the sauce thickens and coats the ingredients.

5-Spread 1 cup of the meat mixture evenly in the casserole dish.

6-Layer 6 corn tortillas (6-inch) on top, slightly overlapping.

7-Spread one-third of the remaining meat mixture over the tortillas, then sprinkle with one-third of the 4 cups shredded cheddar cheese.

8-Repeat the layering of tortillas, meat mixture, and cheese two more times.

9-Cover with foil and bake for 25 minutes.

10-Remove the foil and bake for an additional 15-20 minutes until the cheese is bubbly and golden.

11-Let the dish rest for 10 minutes before slicing. Garnish with 1 tablespoon chopped fresh cilantro, 2 sliced green onions, diced tomatoes, and sour cream before serving.
