Step 1

Preheat grill to medium-high. Cut six 12-inch lengths of heavy-duty foil. Coat each piece with cooking spray.

Step 2

Combine chicken, sweet potatoes, peppers, onion, garlic, salt, chili powder, cumin and oregano in large bowl; stir to coat thoroughly. Evenly divide the chicken mixture among the foil sheets (place on the side coated with cooking spray). Gather together the long ends of each foil piece, then fold up its open ends to form a packet.

Step 3

Cook until the vegetables are tender and lightly charred, turning halfway through, about 20 minutes total. Serve right away (be careful of steam when opening the packets), with lime wedges.
