Pre-heat the waffle maker to medium.
In a medium size bowl, whisk the dry biscuit mix with the onion powder, garlic powder, black pepper and fresh herbs.
Replace the suggested amount of liquid (milk or water) on the biscuit package directions with buttermilk. Mix in the sour cream and the lemon zest and juice.
Brush the waffle maker with melted butter. Place all the biscuit dough into the waffle maker and cook for 6-8 minutes, or until brown.
In a saucepan, heat the hot sauce, Worcestershire sauce and 2 tablespoons butter. Once hot and bubbly, add the chicken and toss it around a bit just to heat it through.
Remove the waffles from waffle maker and top with the Buffalo chicken. Garnish with chopped celery leaves.
