I like tomatoes in fruit salads as well.
The fried green tomatoes around here are usually the unripened ones of several varieties that are fried. A favorite is this one (both green and ripe):

This is from Wikipedia and sums it up well:
Traditional preparation of fried green tomatoes begins by cutting the tomatoes into approximately 1/4-inch (~1 cm) slices. They are then seasoned with salt and pepper, coated with plain, coarse cornmeal, and shallow fried in bacon fat for a few minutes each side, or until golden brown. Shallow frying is preferred, as the tomatoes do not float in the oil, which allows the weight of the tomato to press the cornmeal to the underside of the tomato. This negates the need for a 'wash' (see below).
Alternatives include using breadcrumbs or flour instead of cornmeal, and frying in vegetable oil or other fat.
A 'wash' may be used; in this case, the sliced tomatoes are first dipped in a liquid before the cornmeal is added. This liquid is usually buttermilk, or occasionally beaten egg. Using beaten egg results in a slightly firmer texture than using buttermilk. 'Washes' are used because cornmeal does not readily stick to raw green tomatoes. Adding the liquid helps the cornmeal stay in place during the cooking process. This also results in the coating on the tomato becoming thicker and less crunchy when compared with tomatoes cooked without a 'wash'.
