While the wings are baking, make your sauce. In a food processor or high-speed blender, add the feta, Greek yogurt, mayo, garlic, lemon juice and zest, red wine vinegar, dried oregano, garlic powder, kosher salt, cracked black pepper, and dill. Blend on medium-low for about 30 seconds, scraping down the sides as needed, until the mixture is smooth and creamy.
