You could, of course, add meat. Chopped ham or slices of pepperoni are perfect. Salami is a great choice too. Or lightly cooked chopped bacon.
But I baked this snack at a time when one of my daughters was on a vegetarian diet. I didn’t want to exclude her from enjoying this delicious snack so I made it meatless.

Take the puff pastry out of the freezer and lay flat on a silicone mat or a baking tray lined with non-stick paper. It will thaw fast so while it’s still firm, roll out thinly. It can be a rectangle or square or circle. Trim the edges, optionally, for a cleaner look.
Take a fork and poke holes all over the puff pastry. That’s to allow steam to escape so that the crust does not turn soggy.
Folding the sides in to create a ridge is not a must be I like doing it to prevent the cheese from accidentally dripping off as it melts. That probably won’t happen if you use a meagre amount of cheese but that’s unheard of in our house. The next photo illustrates that.

Thinly sliced tomatoes are arranged on the puff pastry, the tomatoes are smothered with cheese, mushroom slices go on top of the cheese and the mushrooms are covered with more cheese.

The puff pastry with all the pizza toppings go into the preheated oven. After 15 minutes, when the crust is crisp and golden, and the cheese has melted, your cheese and mushroom puff pastry tart is ready to be cut and served.
