I like to use mustard powder instead so I can control the wetness with the mayo. Garlic powder and onion powder and black pepper. Dill pickle on the side (again to control moisture).

I get that. I barely use any mayo, just enough to bind things together. Maybe 1.5 tbsp for 2 sandwiches.
If I have good Mayo on hand (no seed oil nonsense), I go pretty hard on the mayo for myself, but not so hard that it's offputting if I'm sharing, but I fucking love good mayo.
