In a square glass baking dish, stir together garlic, honey, lime juice, soy sauce, ginger and coconut oil.
Add green onions, shrimp, pineapple and red pepper, tossing to coat. Alternately thread 3 pieces green onion, 2 shrimp, 2 pieces pineapple and 2 pieces red pepper onto each of 12 metal or soaked wooden skewers, discarding any excess marinade.
Place skewers on a greased grill over medium-high heat; close lid and grill, turning once, until shrimp are pink and pineapple is lightly charred, 4 to 6 minutes. Remove to platter; sprinkle with toasted sesame seeds.
