3 pizzas came in individual plastic bags. We placed them all on one tray, still frozen and layered them with marinara, fresh veggies, plant-based pepperoni, and Miyoko's liquid mozzarella.

It would be worth baking those toppings on the side, then adding them to the pizza, or pre-baking them for a few minutes, then adding with the rest of the toppings.
