• Preheat the oven to 450 degrees Fahrenheit (220 degrees Celsius). Oil a nonstick baking tray or line it with parchment paper (Note 2).

Dough:

• Place flour, water, yeast, oil, and salt in the kitchen machine or a stand mixer bowl. Knead until the dough is elastic and starts coming off the walls of the bowl. If the dough doesn't release from the bowl's walls, add a pinch of flour and knead for a few more seconds (Note 3).
• Transfer to a lightly floured working surface. Knead briefly to form a ball, flatten it and roll it according to the size of your baking tray (Note 4).
• Oil or line the baking tray and transfer the rolled dough onto it. For easy transfer, lightly fold the dough on the rolling pin and unroll it on the tray. Press it lightly into the corners of the pan and up the sides of the tray.
• Place in a warm place and let rise for 20-30 minutes, usually as long as it takes you to preheat the oven, make the sauce, and chop the rest of the ingredients.

Tomato sauce:

• Make a quick Neapolitan Pizza Sauce or Hearty Marinara. Or use a bought pizza sauce.

Salami or pepperoni pizza:

• Spread tomato sauce on the rolled dough. Sprinkle with mozzarella cubes, sliced onions, and peppers. Cover evenly with the grated cheese. Arrange the salami slices on top.

Margherita pizza:

• Spread tomato sauce on the dough. Arrange mozzarella slices, tomato halves, and black olives on top. Cover evenly with the grated cheese. Add some basil leaves on top before serving.

Ham and mushrooms:

• Spread tomato sauce on the dough. Arrange the cubed ham, drained mushrooms, onion slices, mozzarella cubes on top. Cover evenly with the cheese.

Bake:

• Bake at 450 degrees Fahrenheit (220 degrees Celsius) for 20-25 minutes. If your oven gets hotter, the cooking time might be shorter. Always check!
• The upper side should look cooked through, and the cheese should be melted and golden brown. Check the bottom as well. Lift the pizza on one side using a spatula. It should be cooked through and have a nice brown, bread-like color. If it's not, allow a few more minutes in the oven and check again.
