To make the dough combine the flour, yeast, sugar, and salt in a bowl. Make a well in the center and pour in the water and olive oil.
Mix until the flour in incorporated and a dough has formed.
Turn the dough onto a floured surface and knead it for 5-7 minutes or until it is smooth and elastic.
Shape the dough into a ball and place in a greased bowl. Cover with a clean towel and allow to rise 1 hour or until doubled in size.
Preheat the oven to 400 degrees.
Punch the dough down to release the air. Turn the dough onto a lightly flour surface and roll into a rectangle that is 14β by 8β.
Cut 8 strips on each side of the long side of the dough, about 2 inches deep.
Spread marinara sauce in the middle of the dough where it isn't cut. Sprinkle 3/4 cup of mozzarella cheese on top of the sauce. Place 1/3 cup of pepperoni on top of the cheese. Sprinkle with parsley.
Top with 1/4 cup of mozzarella cheese.
Starting at one end of the dough, fold the first strip from the left over top of the filling and onto the right side. Then take the first strip on the right over top of the filling and onto the left side. Continue alternating sides until the dough looks like it is braided over top of the filling.
Sprinkle with a bit of cheese.
Bake for 20 minutes. Remove from the oven and cut into 12 slices. Serve with marinara dipping sauce.
