Step 1

In a large bowl mix together the flour, yeast, potatoes, oil, and salt, then add just enough warm water to create a dough.

Step 2

Dump the dough onto a lightly floured surface and knead for 5 to 7 minutes, or until smooth and shiny.

Step 3

Place the dough into a lightly oiled bowl and cover with plastic wrap.

Step 4

Place the bowl in a warm spot in the kitchen, and let rise until doubled in size, about 1 hour.

Step 5

Preheat oven to 450 degrees F.

Step 6

Lightly oil a 14 inch round baking pan and press the dough in to fit.

Step 7

Press your fingertips over the top of the dough to create dimples.

Step 8

Place the olives and tomatoes over the dough, then sprinkle with the oregano and coarse salt.

Step 9

Drizzle with olive oil, let rest for 30 minutes, then bake until golden brown, about 20 to 25 minutes.

Step 10

Cool to room temperature before slicing.
