Step 1: Cook the Meat Mixture

In a large frying pan, heat a little oil over medium heat. Add the chopped onion and bell pepper, cooking for 5 minutes until softened. Add the garlic and cook for another minute. Next, add the minced beef (or turkey) and cook until browned all over, breaking it up with a wooden spoon.

Step 2: Add Seasoning and Vegetables

Stir in the cumin, smoked paprika, chili powder, and tomato purée. Let the spices cook for a minute to release their flavor. Then add the diced tomatoes, black beans, sweetcorn, and stock. Season with salt and pepper. Simmer the mixture for about 10-15 minutes, allowing the sauce to reduce and thicken slightly.

Step 3: Assemble the Mexican Lasagne

Preheat your oven to 180°C (350°F). In a large ovenproof dish, spread a thin layer of the meat mixture on the bottom. Lay 2-3 tortillas on top of the meat, overlapping them slightly if needed. Add another layer of the meat mixture, followed by a sprinkle of grated cheddar and mozzarella cheese. Repeat the layers until you’ve used all the meat mixture and tortillas, finishing with a generous layer of cheese on top.

Step 4: Bake the Lasagne

Place the dish in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and golden brown. The filling should be bubbling, and the top should have a nice crispy layer of cheese.

Step 5: Serve

Once baked, remove the lasagne from the oven and let it cool for a few minutes before slicing. Garnish with fresh coriander, and serve with optional toppings like sour cream, sliced avocado, or jalapeños.
