Beef and Peach Skewers

1 large onion, cut in 1/2" slices
1 large peach, cut in 1/2" slices
6 oz. portabellas, sliced in half, then half again
1 lb. lean grilling steaks (tenderloin or sirloin), cut into 1" cubes
wooden skewers
1 T. brown sugar
1 t. kosher salt
1 t. curry powder
1 lime
1 T. sriracha, or ground chilies, optional

Preheat grill. Place beef, onions, mushrooms, and peaches into skewers (alternating between each). Combine brown sugar, salt, and curry. Coat skewers with seasoning, then coat with cooking spray. Grill 8-10 minutes, turning occasionally until meat is 145 degrees. Remove from grill. Squeeze lime juice over skewers, drizzle with sriracha, and serve. May be served over Farro salad, rice, or quinoa, if desired.
