Place sliced tomatoes onto a paper towel, lightly salt them with kosher salt.
Allow tomatoes to sit for 5 minutes.
Top with another layer of paper towel to absorb some of the moisture and blot them.
Preheat oven to 400°
Prepare pie crust, roll out crust to about 14" round. If you buy pie crust just roll it a little to smooth and soften it.
Place the pie crust on a parchment-lined baking sheet or baking screen.
Top the pie crust with garlic paste or garlic powder mixed with a little oil to spread easily over the bottom of the pie crust, about 10" round.
Place the mozzarella cheese, then the sliced tomato.
Add the oregano, salt, and pepper along with Romano or Parmesan cheese.
Fold the outer edge of the pie over the filling about 2 inches of overlap.
Brush the edge of the pie crust with heavy cream.
Bake in the 400° oven for 25-28 minutes or until the pie crust is fully cooked and golden on the bottom, lift the crust up with a spatula to be sure it's firm and cooked.
Remove from the oven and allow it to cool for 10 minutes.
Slice and serve.
