How to Make It
Heat 1 tablespoon oil in a medium saucepan over medium. Add shallots and garlic; cook 3 minutes, stirring occasionally. Stir in cherries, walnuts, sage, and minced thyme; cook 2 minutes. Add port and honey, scraping pan. Bring to a simmer; cook 3 minutes or until syrupy. Stir in 1/4 teaspoon salt and 1/4 teaspoon pepper. Cool slightly.
Preheat grill to high.
Debone trout (optional), removing spine and ribs with a fillet knife; leave head, tail, and skin intact. Brush fish, inside and out, with remaining 2 tablespoons oil; season with remaining 3/4 teaspoon salt and 1/2 teaspoon pepper. Stuff cavities with thyme sprigs.
Place trout, skin side down, on grill grates coated with cooking spray. Cover and grill for 6 to 8 minutes or until flesh flakes easily when tested with a fork. Serve with cherry compote and lemon wedges.
