Preheat oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.

In a large skillet over medium heat, cook the ground beef until browned. Drain excess fat.

Add diced onion and minced garlic to the skillet. Cook until onion is translucent, about 3-4 minutes.

Stir in taco seasoning and 1/4 cup of water. Simmer for 5 minutes until mixture thickens. Remove from heat.

Warm tortillas in a dry skillet or microwave for 20 seconds to make them pliable.

Spread 1/4 cup of enchilada sauce in the bottom of the prepared baking dish.

Fill each tortilla with beef mixture and a sprinkle of cheese. Roll up and place seam-side down in the dish.

Pour remaining enchilada sauce over the top and sprinkle with remaining cheese.

Bake for 20-25 minutes until cheese is melted and bubbly.

Garnish with cilantro, sour cream, tomatoes, and olives if desired before serving.
