Preheat your oven to 400° F.
Line a baking sheet with parchment paper. The size doesn't matter, just whatever size your puff pastry is!
Roll out your puff pastry to your desired size. I just try to roll it out to about the size of whatever sheet I'm using. Layout the puff pastry on the baking sheet.
Lay your sliced tomatoes on a paper towel and season with salt and pepper. Let them sit for 5-10 minutes, flip them, and do the same thing. This is to drain the tomatoes so that they don't make the puff pastry soggy.
In a bowl, combine the ricotta, basil, parsley, garlic, pepper, and salt.
Spread the ricotta mixture over the puff pastry.
Lay your tomatoes on top. Top with additional basil, salt, and pepper if you'd like.
Bake for 10-15 minutes, or until the puff pastry edges are golden. This will be different for every oven so make sure to keep checking.
