1/2 cup Mayo
2 tbsp ketchup
2 tbsp mustard (I would personally only use one next time, little bit too tangy for me)
2 tbsp diced pickles
2 tbsp diced onions
1tsp paprika
1tsp onion powder
Salt pepper to taste
Let it sit in the fridge a few hours
This amount makes enough sauce for about 4 of these. Double as needed
