1 teaspoon instant yeast
2 tablespoons olive oil
2 teaspoons salt
1 cup lukewarm water
1 cup creme fraiche
2 medium or one large yellow onion, thinly sliced
1 tablespoon olive oil

Add first five ingredients (flour through water) in the pan of your bread machine and set on dough setting. When cycle is complete, roll out dough on a well floured surface as thin as possible. Preheat oven to 450 degrees Fahrenheit. Transfer rolled out dough on a baking stone, spread creme fraiche, and sprinkle with speck or grated cheese. Bake in preheated oven for 15-20 minutes or until done.
