I avoid salt. I like garlic, oregano, fresh ground pepper, and basil. Although it's not a spice, I think that a little grated parmesan cheese adds a delicious flavor to many dishes. Lemon is nice also.
If you are new to using herbs and spices, you can buy a spice rack that contains spices. You can try them and decide what you like. It's a good way to get started.
