Prepare the grill by heating it to medium-high temperature. Give the wings some flavor by seasoning them with a sprinkle of salt and pepper.
Using your grill tongs, dip a bunch of paper towels into some oil and gently rub the grill grate until it becomes glossy and coated.
After that, grill your wings while keeping the lid down and occasionally turning them over until they become crispy and golden brown, and are completely cooked through. This should take about 20 minutes. Make sure to keep a watchful eye on the grill, and if you notice any flare-ups or the wings beginning to burn, move them to a cooler part of the grill or reduce the heat. It's important to avoid getting grill marks on the wings, instead strive for an even and delightful golden-brown color.
As the wings cook, prepare the sauce. Mix together the garlic and butter in a bowl that is safe for the microwave. Heat the mixture in the microwave for around one minute until the butter melts. Add the hot sauce, salt, onion powder, chili powder, and sugar to the melted butter and stir well. Keep the sauce in a separate bowl for later use.
After cooking the wings, submerge them in the sauce and promptly serve.Alternatively, you can pair the wings with grilled vegetables and provide the sauce as a side option.
