For an even deeper flavor, consider adding a splash of sesame oil to the marinade. If you don't have coconut aminos, soy sauce or tamari can be used as a substitute. Feel free to customize the vegetables on the skewers to your liking. Cherry tomatoes, mushrooms, or bell peppers in different colors would all be great additions. To prevent the wooden skewers from burning, soak them in water for at least 30 minutes before threading the ingredients.
