Thaw the puff pastry according to the directions on the package (let sit at room temperature for an hour, or overnight in the fridge).
Preheat the oven to 400 F.
On a lightly floured surface, roll the pastry dough out to a 16"x10" rectangle. With a knife, lightly score a border 1" from the edge. Do not cut all the way through.
With a fork, prick the area inside the border in 1" intervals.
Bake on a parchment-lined baking sheet for 15 minutes, or until golden.
While the pastry is baking, chop the mint leaves and mix with the goat cheese.
Remove the pastry and evenly spread the goat cheese inside the perforated edge on the pastry.
Top with the peas, cherry tomatoes, and a good dose of pepper. Lightly brush the edges of the pastry with olive oil.
Bake until the tomatoes have slightly softened, another 10-15 minutes.
Cut into small squares to serve.
