Spicy Sauce: Add Roma tomatoes into a blender. Add chili flakes and season with olive oil, salt and pepper. Pulse the blender a few times until evenly chopped (some chunkiness is good) and leave to the side.
For the pizza gremolata, add cilantro, parsley and zest of 1 lemon, 1 lime and 1 orange into a food processor. Season with salt and pepper and pulse, adding a little olive oil to blend. Once blended, move to the side.
Grate mozzarella to your liking and set to the side.
Stretch the pizza dough out thin and round – using a rolling pin if necessary.
Spread chunky tomato sauce all the way to the edge leaving room for a little crust. Use as much sauce as needed. Generously spread salami all over the pizza.
Cook the pizza in the 5 Minute Pizza Oven & Snack Maker until golden brown and crispy (about 5 minutes).
After pizza is cooked, garnish with the gremolata and serve.
