Preparation:

Step 1:
Heat olive oil in a skillet over medium heat. Add the diced onion and sauté until it becomes soft and translucent, about 3-4 minutes.

Step 2:
Add the ground beef to the skillet. Cook, breaking it up with a spatula, until it is fully browned. Sprinkle in the garlic powder, ground cumin, paprika, salt, and pepper. Continue to cook, stirring occasionally, until the beef is evenly seasoned.

Step 3:
Once the beef is cooked through, remove the skillet from the heat. Drain any excess grease, then set the beef mixture aside.

Step 4:
In a clean skillet, melt 1 tablespoon of butter over medium heat. Place one tortilla into the skillet. Sprinkle a layer of shredded cheese over half of the tortilla, then add a portion of the beef mixture on top of the cheese. Add more cheese on top of the beef to ensure every bite is cheesy.

Step 5:
Fold the tortilla in half and cook until it is golden brown and crispy on one side (about 2-3 minutes). Flip and cook the other side for another 2-3 minutes. Repeat with the remaining tortillas, adding more butter as needed.
