In a large skillet, heat a drizzle of oil over medium heat. Add the chopped onion and sauté until softened (about 2-3 minutes).

Toss in the ground beef while breaking it apart with a spatula. Cook until browned, approximately 5-7 minutes. Season with salt, pepper, and taco seasoning.

Once the beef is cooked through, stir in the refried beans and salsa. Ensure everything is well blended and heated through (another 2-3 minutes is usually sufficient).

Lay a tortilla flat on a clean surface. Spoon a generous amount of the beef mixture onto the center of the tortilla and sprinkle it with a handful of shredded cheese.

Fold the sides inwards, then roll it up from the bottom to the top, creating a burrito shape.

In the same skillet (or a different one), place the burritos seam side down and grill them for about 2-3 minutes on each side until they are golden and crispy.

Remove from the skillet, slice in half if desired, and serve with your favorite toppings!
