Ham, Pineapple, and Red Onion Pizza

For Pizza Dough:

In a small bowl, combine warm water and yeast. Let stand until the yeast dissolves, about 5 minutes.

Mix the flour and salt in a food processor. Blend in the oil. With the machine running, add the yeast mixture and blend just until the dough forms. Turn the dough out onto a lightly floured work surface and knead until smooth, about 1 minute. Transfer the dough to a large oiled bowl and turn the dough to coat with the oil. Cover the bowl with plastic wrap and set aside in a warm draft-free area until the dough doubles in volume, about 1 hour. Punch the dough down and divide into 2 equal balls.

Position one oven rack in the center and the second rack on the bottom of the oven and preheat to 450º F / 230º C. Sprinkle cornmeal over 2 rimless baking sheets.

On a lightly floured surface, roll out each dough ball into a 10 to 11-inch / 28 to 28 cm round and place on prepared baking sheets.

For the Topping:

Spoon the marinara sauce over the dough, leaving a 1-inch border around each pizza edge. Sprinkle the cheeses over the sauce. Arrange the pineapple pieces in a single layer over the cheeses. Sprinkle with the ham and red onion. Season to taste with Italian seasoning.
