I use any combination of these, sometimes not all...but I have used them all before.
Salt
Pepper
Paprika
Parmesan & Ramano Cheese
Garlic Salt
Cracked Black Pepper
Basil
Oregano
Thyme
Rosemary
Majoran
This stuff called Butter buds (don't use much, but I do put it in there.)
and I mix Bread Crumbs in with the flour to give it a good crunch.
