How to Make It
Place a large cast-iron skillet in oven; preheat oven to 400°.
Combine first 6 ingredients in a small bowl. Spread ricotta mixture evenly over crust, leaving a 1/2-inch border around the edges. Place crust on preheated cast-iron pan.
Bake in the center of the oven at 400° for 12 minutes or until crust is crisp. Place crust on a cutting board. Sprinkle evenly with chives and pepper; cut into 16 pieces. Serve warm or at room temperature.
