Preheat the oven to 350°F (175°C).

In a large skillet, heat a splash of oil over medium heat and add the diced onion. Cook until softened, about 5 minutes, then add the garlic and sauté for another minute.

Add the ground beef to the skillet and break it apart with a spatula. Cook until browned, about 7-10 minutes, ensuring it's fully cooked through.

Stir in the chili powder, cumin, salt, and black pepper.

Lay out the flour tortillas on a clean surface. Spoon a portion of the beef mixture onto each tortilla, followed by a sprinkle of cheese.

Fold in the sides of the tortilla and roll tightly from the bottom up.

Place the rolled enchiritos seam-side down in a baking dish. Pour the enchilada sauce over the top and sprinkle with remaining cheese.

Bake in the preheated oven for about 20 minutes, or until the cheese is melted and bubbly.
