  2. Pull pastry out of oven, and take the flat part of a fork and smash middle that has puffed up down.

  3. Top with cherry tomatoes, cut side up. Add a few grinds of fresh pepper, and top with remaining parmesan cheese.
  4. Bake for a total of 30 minutes, turning half way through. If side crust is getting brown, and tomatoes have not quite cooked, cover lightly with foil.

Notes

The type of cheese you should use should be a hard, tangy, flavorful cheese. We have used many varieties of sharp cheese combos, and they all turn out so good. Recently we used a whiskey white cheddar along with a drunken goat cheese. Winner combo for sure!
