Next time you're hosting a gathering of friends, here's a great deal to keep in mind: Buy five medium or large pizzas and the sixth is free. Lots of toppings to choose from, including feta cheese, anchovy, pineapple, garlic and eggplant. You'll also find more than a dozen gourmet pizza concoctions. Not in the mood for pizza? Try the subs, club sandwiches, pasta dishes, fresh salads or dinner plates.
