Our farmers use lemon basil all the time. It is often served with rice and other dishes, much like you would garnish something with cilantro. Try it in a potato soup like Farmer Tri Sa makes. It also makes a great pesto. More lemon basil ideas here.
STORAGE: All basil is tricky to store well. It is best eaten, made into tea, or turned into pesto right away. If you must store it, place it in a jar of water like a bouquet and keep it on your counter. It may wilt some but it will still be tasty.
