Stuffed Tex-Mex Burgers Recipe

Directions:

1. Process first 5 ingredients in a food processor or blender until smooth; chill.
2. Preheat grill to medium-high (350° to 400°). Combine ground chuck, onion, and salt; shape into 12 (4-inch) patties. Fold cheese slices into quarters; top 6 patties with folded cheese slice. Cover cheese with remaining 6 patties; pressing to seal edges.
3. Grill patties, covered with grill lid, over medium-high heat 5 minutes on each side or until done. For grown-up servings, serve burgers on buns with 2 tablespoons guacamole, 1 tablespoon mayonnaise mixture, and desired toppings. For plain servings, serve burgers on buns without the guacamole and mayonnaise mixture.
