Preheat grill pan, griddle, skillet, or outdoor grill to medium-high heat.
In a large bowl, use your hands to gently combine chicken and seasoning.
Divide meat into 8 equal patties.
Drizzle patties with olive oil (about 1 teaspoon). Cook patties about 5 minutes per side, or until just cooked through.
Meanwhile, in a large skillet over medium-high heat, sauté peppers and onions in about 1 teaspoon of olive oil. Season with salt and pepper and cook until tender (about 8-10 minutes).
When the burgers are cooked, top each patty with ½ slice of cheddar cheese. Cover loosely with foil and let sit for about 2 minutes (or until the cheese is melted).
Just before serving, place each burger on a bun and top with peppers and onions, as well as salsa, guacamole and/or sour cream.
Notes
*I like 92% lean ground chicken – anything with less fat than that will result in a dry burger!
