Preheat oven to 400F
Defrost puff pastry sheet and cut into 9 even squares. Poke each one with fork a few times
Cover cookie sheet with parchment paper and oil spray( i used coconut oil spray). Move all pastry squares to the sheet and spread evenly.
Cover each square with mozzarella first, then add tomato on top. Bake in the oven for 20 min.
While tarts are baking, cook bacon . Place 3 stripes on a hot pan and fry until crispy. Once done, move to the paper towel until cool off and then chop.
Once tarts are done, take them out of the oven and top with goat cheese, bacon bites and arugula. Serve immediately
