Prepare the Dough:

Dissolve sugar and yeast in warm water and let it sit until frothy, about 5-10 minutes.
Mix flour and salt in a large bowl. Add the yeast mixture and olive oil, combining to form a dough.
Knead on a floured surface until smooth, about 10 minutes. Place in an oiled bowl, cover, and let rise for 1-2 hours, until doubled in size.

Preheat the Oven:

Place a pizza stone or inverted baking sheet in the oven. Preheat to 500°F (260°C) for at least 30 minutes.

Assemble the Pizza:

Stretch the dough into a 12-inch circle on a floured surface or parchment paper.
Spread tomato sauce over the dough, leaving a border for the crust. Distribute the mozzarella cheese evenly, then top with ham, artichoke hearts, mushrooms, and olives. Drizzle with a bit of olive oil and season with salt and pepper.

Bake the Pizza:

Transfer the pizza (on parchment if using) to the preheated stone or sheet. Bake for 10-12 minutes, until the crust is golden and cheese is bubbly.

Serve:

Remove from the oven, let it cool for a few minutes, then slice and serve.
