Herb-Stuffed Grilled Trout

Prepare the fish: Preheat grill to medium high. Place the trout on a clean work surface. Evenly divide the thyme, red onion, salt, and pepper among the 4 trout and place in the cavity of each. Rub the outside of each trout with the oil and set aside. Cut twelve 10-inch lengths of kitchen twine; tie 3 around the body of each trout to secure the herb stuffing.

Cook the trout: Place the trout in a large grill basket and cook directly on the grill rack for about 7 minutes. Flip the grill basket over and continue cooking until opaque in the center -- about 7 more minutes. Remove twine and serve immediately.
