1. Roll out your dough onto a pizza pan and spread pesto all over as the base sauce. Then place your roasted vegetable on top starting with the tomatoes and then the onions after (you can take the onion slices apart when you’re layering so it layers well).
2. Take a chicken scissor and cut your chicken and pastrami into small pieces and scatter all around on top of the vegetables. (You can cut the chicken to whatever size you prefer, but it’s easier to eat the pizza when they are smaller pieces).
3. Bake like instructed on dough package.
4. Drizzle garlic mayo over it before you serve.
