"I was in Guadalajara and had a burger similar to this one," Assistant Food Stylist Kathleen Kanen reports. The salsa that topped the burger was a welcome change from the usual tomato and onion slices, and Kathleen added tequila to her version. The recipe makes more salsa than you'll need for the burgers; serve the extra on the side with baked tortilla chips.
Combine chile powder, salt, and beef. Divide the mixture into 4 equal portions, shaping each portion into a 1/2-inch-thick patty.
Place patties on a grill rack coated with cooking spray; grill 5 minutes on each side or until done. Place rolls, cut sides down, on grill rack; grill 1 minute or until toasted. Place 1 patty on bottom half of each roll; top each serving with 1/3 cup Tequila-Spiked Salsa and top half of roll.
