How to Make It
Form the beef into four ½-inch-thick patties and season with the paprika, ½ teaspoon salt, and ¼ teaspoon pepper.
Heat the oil in a large skillet over medium-high heat. Cook the patties for 3 to 4 minutes per side for medium-rare. During the last minute of cooking, top the burgers with the cheese and cook, covered.
Serve the burgers on the buns with the salsa and the avocado.
