1. Preheat your oven to 400°F. Spread the frozen fries on a baking sheet in a single layer and bake according to package instructions.
2. In a large skillet, heat olive oil over medium heat. Add chopped onion and cook until translucent, about 5 minutes.
3. Add minced garlic and cook for another minute until fragrant.
4. Add ground beef to the skillet and cook until browned, breaking it apart with a wooden spoon, about 7-10 minutes.
5. Stir in cumin, chili powder, salt, and pepper, and cook for an additional 2 minutes to let the spices bloom.
6. Mix in the salsa and let the mixture simmer for 5 minutes to meld the flavors.
7. Warm the flour tortillas in a dry pan or microwave to make them pliable.
8. Place a portion of the beef mixture on each tortilla, sprinkle with cheddar cheese, and roll up tightly.
9. Once the fries are crispy and golden, remove them from the oven and serve alongside the burritos.

A little tip: Warming the tortillas beforehand makes rolling much easier and prevents them from cracking. This was a trick I learned from my grandmother, who always knew the little things that made a big difference.
