Creating Beef Quesadillas is a simple and rewarding process. Follow these steps for a delicious outcome:

1. Cook the Beef: In a skillet over medium heat, add the ground beef and cook until browned. Drain excess fat.

2. Add Aromatics: To the skillet, add the diced onion and minced garlic. Sauté until the onion is translucent, about 3-4 minutes.

3. Season: Stir in the chili powder, cumin, salt, and pepper. Mix well and cook for another minute to combine the flavors.

4. Prepare the Tortillas: On a separate skillet or griddle over low heat, lightly brush or spray with oil.

5. Layer Ingredients: Place one tortilla in the skillet, then sprinkle half of the shredded cheese over it. Spread an even layer of the beef mixture on top of the cheese.

6. Top It Off: Add more shredded cheese on top of the beef mixture, and place a second tortilla on top.

7. Cook: Allow the quesadilla to cook for 3-4 minutes or until the bottom tortilla is golden brown and crispy. Carefully flip the quesadilla using a spatula, and cook the other side for another 3-4 minutes.

8. Complete the Cooking: Once both sides are golden and the cheese is melted, remove the quesadilla from the skillet. Transfer to a cutting board.

9. Slice: Cut into wedges for easy serving.

10. Repeat: Repeat the process with the remaining tortillas, beef mixture, and cheese until all quesadillas are prepared.
