-
1 teaspoon kosher salt, divided
-
1 teaspoon black pepper, divided
-
2 ounces sharp Cheddar cheese, shredded (about ½ cup)
-
4 thick red onion slices
-
4 whole-wheat hamburger buns, split

Description
-
Preheat grill to medium high. Gently mix together the sirloin, bacon, and ½ teaspoon each salt and pepper in a medium bowl. Shape the mixture into 4 (½-inch- thick) patties. Press your thumb gently into the center of each patty to make an indentation.
-
Season the patties with the remaining ½ teaspoon of salt and pepper. Grill until nicely charred on 1 side, about 4 minutes. Flip and cook 2 minutes. Divide the Cheddar among the patties, cover, and cook until melted, about 2 minutes more.
-
Meanwhile, grill the onion slices, flipping once, until lightly charred and tender, about 4 minutes. Grill the buns, cut-side down, until lightly toasted, about 1 minute.
-
Stir together the mayonnaise, ketchup, and Sriracha in a small bowl. Top the bun bottoms with the patties, onion slices, spinach, and pickles. Divide the mayonnaise mixture among the bun tops and place on the burgers.
