Preheat the oven to 350F.

Heat the oil in a large pan and add the ground beef. Cook until the meat has browned all over. Drain the meat if there is excess liquid.

Add the salsa and cook for 10 minutes or until most of the liquid has evaporated. Season with salt and pepper if necessary. Add hot sauce or chipotle powder as required.

Layer the tortillas with the meat mixture in a baking dish, cutting the tortillas to fit as necessary.

Sprinkle the cheese over the top and bake until the cheese has melted and golden brown, approximately 10-15 minutes.

Garnish with fresh cilantro and serve.
