For the Fries:

1. Preheat Oven: Preheat your oven to 425°F (220°C).
2. Prepare Fries: If using fresh potatoes, cut them into thin fries and toss them in olive oil, paprika, garlic powder, salt, and pepper. Spread the fries in a single layer on a baking sheet.
3. Bake Fries: Bake the fries for 25-30 minutes, flipping halfway through, until they are crispy and golden brown. (If using frozen fries, follow package instructions for baking.)

For the Burritos:

1. Cook Beef: In a large skillet over medium heat, cook the ground beef until browned and fully cooked, breaking it apart with a spoon as it cooks. Drain any excess grease.
2. Season the Beef: Add the taco seasoning and water to the cooked beef, and stir to combine. Let it simmer for 3-4 minutes, or until the sauce thickens and is well-coated on the beef.
3. Assemble Burritos: Lay the flour tortillas flat on a clean surface. Spread a small amount of sour cream on each tortilla. Add a generous amount of the seasoned beef mixture, top with shredded cheese, and add salsa, onions, cilantro, and jalapeños if using.
4. Roll Up Burritos: Fold in the sides of the tortillas and roll them up tightly, ensuring the filling stays secure.
5. Serve: Serve the cheesy beef burritos with the crispy fries on the side. Garnish with extra cilantro or parsley if desired.
