In a skillet over medium heat, cook the ground beef and diced onion until the meat is browned and the onions are soft.
Drain excess grease, then add taco seasoning and water. Stir and let simmer for 5 minutes.
Lay each tortilla flat and fill with a portion of seasoned beef, cooked French fries, and shredded cheddar cheese.
Roll each tortilla into a burrito, folding in the sides and rolling tightly.
Heat a skillet over medium heat and lightly coat with oil or cooking spray.
Place each burrito seam-side down and cook until golden brown and crispy, about 2-3 minutes per side.
Serve hot with your favorite dipping sauces or a side salad.
