Falafel Chicken Burgers with Lemon Sauce

Directions

1. If desired, prepare onion rings according to package directions.
2. Meanwhile, in a small bowl, mix sauce ingredients. In a large bowl, mix the first 7 burger ingredients. Add chicken; mix lightly but thoroughly. Shape into four 1/2-in.-thick patties. Place 1/2 cup falafel mix in a shallow bowl (save remaining mix for another use). Press patties into falafel mix, patting to help coating adhere.
3. In a large nonstick skillet, heat oil over medium-high heat. Add burgers; cook 4-5 minutes on each side or until a thermometer reads 165°. Serve burgers on buns with sauce and arugula; if desired, add an onion ring, sliced tomato and cucumber slices to each.
