If you use only salt, black pepper, garlic, and a little lemon juice, it is already very tasty. You can add paprika or smoked paprika. Sometimes I add an "Italian herb blend" or other blends that contain basil, oregano, parsley, dill, thyme and marjoram. But it turns out really good without them, too! )

Yes, I forgot the mustard. Sometimes I add a little, sometimes quite a lot. And so and so tasty, but in different ways.
