In a medium bowl, combine meat with 2 tablespoons bbq sauce, chili powder, salt and pepper. Mix well to combine and form into 6 patties about ½-inch thick.

Heat a large non-stick sauté pan over medium high heat and spray with cooking spray. Cook patties 5 to 7 minutes per side or until a nice brown crust is formed and middle is still pink. Let sit 5 minutes.

To assemble sliders, place a slice of red onion on the bottom of bun. Top with patty, 1 tablespoon bbq sauce and top of bun. Serve with onion rings baked according to package directions.
