Wow some great ideas for pizza's. I have to try them with my kids and Uncle Bob that pictures looks fabulous and if I can grab it I would and take a bite
I would say the following:
Thai Style - Grated carrots, bean sprouts, cilantro, chopped peanuts, scallions. Sauce is a combination of peanut sauce, coconut milk, soy sauce, spices. You can put cheese or skip it.
Chicken Tikka Masala Pizza - Sounds odd but tastes super. Chicken Breasts cut into small chunks. Marinated in yogurt and Indian spices and cooked in a pan or better yet on a grill for a charred flavor. Also lots of freshly chopped cilantro. Sauce is a rich tomato, butter and cream sauce with spices like corrainder, cumin, chilis etc. Thick sauce goes first, then a sprinkle of the cooked chicken and cilantro, Cheese is optional.
Buffalo Chicken - I love this one and it's really easy to make. Get ready made frozen chicken nuggets (should be the premium kind made with white meat). Bake them in the oven until crispy. Make a sauce with hot sauce and butter. Cut the nuggets into two. First goes the hot sauce on the pizza then the chicken is arranged, then some more hot sauce is brushed, cheese and bake and enjoy.
Fajita Pizza - Assorted mix of chicken, steak, veggies or whatever you like. I cook mine on a grill pan. Sauce - Similar to a salsa, with tomatoes, green chilis, cilantro and garlic. Put sauce, put the veggies and meat, put cheese and bake and enjoy
