Preheat your oven to 375°F (190°C).

In a large skillet, heat oil over medium heat. Add ground beef and diced onions, cooking for 5-7 minutes until browned.

Stir in minced garlic, cumin, and chili powder, cooking for an additional minute.

Lightly fry tortillas in a hot pan for about 30 seconds per side until pliable.

Spoon beef mixture into tortillas, roll tightly, and place seam-side down in a greased baking dish.

Pour enchilada sauce over rolled tortillas and sprinkle shredded cheese on top.

Bake uncovered for 20-25 minutes until cheese is bubbling and golden.

Garnish with chopped cilantro or jalapeños, if desired, and serve warm.
