This is the recipe I use to season all my food. I actually double and sometimes triple this recipe.
1 c. salt (I use kosher salt, but regular salt is fine too)
1/4 c. garlic powder
1/4 c. onion powder
1/8 c. pepper
Mix all of this together in a tupperware container, with lid…shake before you use it and sprinkle on anything you would normally season.
