Combine first 6 ingredients. Divide mixture into 4 equal portions, shaping each into a 1/2-inch-thick patty.
Heat a large nonstick skillet over medium-high heat. Coat pan with cooking spray. Add patties to pan; cook for 4 minutes on each side or until a meat thermometer registers 160°.
Combine coleslaw and next 6 ingredients (through pepper) in a large bowl; toss well. Place 1 patty on bottom half of each bun; top each serving with 1/2 cup coleslaw mixture and top half of bun.
