Position the lower oven rack on the bottom third of the oven and preheat the oven to 450 degrees (F).
Pat the wings dry and sprinkle them with Kosher salt and ground pepper, to taste. Spread the wings out evenly in a 9x13 baking dish and bake the wings, flipping them over halfway through, for 40 minutes.
While the wings are baking, combine in a food processor or blender the huckleberries, low-sodium soy sauce, rice wine vinegar, light brown sugar, olive oil, garlic, roasted sesame seeds, red pepper flakes and ground ginger. Blend until sauce is smooth. Transfer the huckleberry sauce to a small saucepan and simmer on low until slightly reduced.
Once the wings are done baking, remove the wings from the baking dish and place them in the large bowl with the huckleberry sauce. Toss the wings until fully coated with the sauce and then return the wings to the baking dish to continue baking for 3-5 minutes until glazed.
Plate the wings and garnish them with sesame seeds and green onion.
