Preheat oven to 450 degrees. Sauté the onion in the butter and oil over medium heat until softened but not browned. Roll out pizza dough on a lightly floured surface into a rectangle approx. 8”x16”. Cut dough in half to form two 8x8 squares. Spread onion mixture evenly over dough. Top with cheese, black olives, and anchovies. Roll dough into a log. Gently holding log together, slice into ½“ rounds. Place on an oiled cookie sheet and tidy up the round shapes. Leave a little space between rounds to allow dough to rise. Bake 20 minutes until risen and golden brown. Serve warm or at room temperature.
Chef's Notes:
Variations: use cheddar with pimento stuffed green olives, or kalamata olives (rinse kalamatas or rolls will be too salty.)
