I love using it as a salad green, especially the Black Opal basil (lovely purple leaves and stems)
Really, I have found many herbs quite easy to grow, and many of them, such as rosemary and lavender, prefer a minerally soil that is a bit dry, so if I want to grow something in the parts of my yard that are too poor for veggies, and don't want to amend, the herbs do great there.
Any sunny patch in a temperate climate I would try sticking some thyme and rosemary, and see what you get - they will go for years. Mint and lemon balm like a damper location, and can stand some shade - but watch out, because mint will take over.
Fresh mint and thyme together make a really nice and tasty tea that is soothing for coughs and colds.
