This is beyond easy and you will look like a rock star. All you need is a tart tin. I actually made two. One circular and one triangular.
One box of frozen puff pastry
2 pints of cherry tomatoes
Basil – cut into thin slices
Olive oil and kosher salt
Preheat the oven to 350.
Let the puff pastry defrost. Unfold it and then lay it over a floured surface. Roll it out to be about twice the size. I was able to use one box to make two tarts. Lay the pastry over the tart tin and crimp into the tart.
In a separate bowl put the cherry tomatoes and mix with olive oil and kosher salt. Pour these into the tart. Place the tart tin over a cookie sheet and put in the oven. Bake for about 30 minutes or until the pastry is browned.
Sprinkle the basil over the top.
Serve warm or at a room temperature.
Note: I put shaved Gruyere underneath the tomatoes. It is fine if you serve the tart warm but once it gets to room temperature it becomes a little mushy.
