put the flour in the bowl of a stand mixer
put the salt on one side of the bowl, and the yeast on the other side
pour water in the bowl
and stir to combine
once the ingredients are stirred together let the machine knead for about 4-5 minutes until a smooth wet dough is formed
oil a container for the dough and scrape the dough in, cover, and let it rest
once it's doubled
grease an 8X12X2 baking pan (9X13 would work too!) and gently ease the dough into the pan
coax it to the edges or close to them anyway
cover and let rise again for 40 minutes or until the dough comes up the top edge of the pan
preheat the oven to 425˚
meanwhile, slice tomatoes in half, or if using bigger tomatoes just cut slices, and break up rosemary into little sprigs
when the dough has risen almost to the top of your pan poke all over and drizzle with oil
place cut tomatoes all over the top, press in lightly, scatter with rosemary
bake in the preheated oven for 20-25 minutes or until the center is baked
