Step 1: Preheat your oven to 350°F (175°C) to ensure even cooking.
Step 2: In a large mixing bowl, combine the drained black beans, vegetable broth, chili powder, cumin, black pepper, and salt. Stir until well mixed.
Step 3: In your greased 9x13 inch baking dish, layer half of the torn whole-grain tortillas on the bottom.
Step 4: Pour half of the black bean mixture over the tortilla layer, spreading it out evenly.
Step 5: Add half of the salsa on top, followed by half of the shredded Mexican cheese and half of the sliced jalapeños.
Step 6: Repeat by layering the remaining tortillas, black bean mixture, salsa, cheese, and jalapeños on top.
Step 7: Cover with aluminum foil and bake for 25 minutes, then remove the foil and bake for an additional 15 minutes or until the cheese is melted and bubbly.
Step 8: Let cool for a few minutes before serving. Enjoy!
