There is a local pizza place where I live that has a few popular pies that I consider to be non-traditional, but that may depend on where you live. I haven't personally tried any of these so I'm just going to post the descriptions straight from their website.
Hibachi Pizza
Japanese white sauce (yum-yum sauce), chicken, shrimp, sautéed broccoli, carrots, mushrooms, zucchini, onions, fried rice, and an oyster/soy sauce combination, finished with sesame seeds.
Korean Beef
Korean BBQ sauce, seasoned ground beef, fried rice, carrots, scallions, cilantro, fried onions, and mozzarella
Crab Rangoon
Crab Surimi, Cream Cheese, Sweet Peppers, Mozzarella, Crispy Wontons, Scallion, Sweet Chili Sauce, Spices
Paige's Delight
Marinated grilled chicken breast, Apple-wood smoked bacon & onions on a sweet glaze, topped with our Mozzarella cheese blend, cilantro, fresh strawberries, and hot chili sauce.
I'm not really sure how I feel about these. I wouldn't be against trying them if they were in front of me. Maybe I would like them. I'm just not willing to spend my own money to find out. So, if you're ever in my neck of the woods, I'll be more than happy to show you around and let you buy me lunch.
