A quick and easy fry sauce

So my husband doesn't like ketchup and I only eat it occasionally.  We really really enjoy a sauce I found on Pinterest a while back called Comeback Sauce.  It has about 1000 ingredients and takes a little more time. So I found a different version with less ingredients and still tastes yummy.  I doubled the recipe for a family of 4. Although I left out half the salt and pepper because I didn't want it too spicy for my girls.

Fry Sauce
1/4 cup of mayo
2 tbsp ketchup
1 tsp vinegar
1/2 tsp black pepper
1/2 tsp season salt
