Tomato Basil Squares

I made tomato basil squares last weekend as an appetizer for my birthday. My aunt typically makes this dish for every family party, and it has become one of my favorite savory "family recipes". It is really easy to make, and requires few ingredients and little prep time. And it is oh so delicious.
Depending on how you cut this, serves approximately 16 squares.

Ingredients
1 Package of pizza dough
2 Cups (8oz) shredded Mozzarella cheese, divided
1 Ounce (1/4 cup)fresh parmesan cheese grated (I buy the grated cheese)
2 Tablespoons fresh basil leaves, snipped or 2 teaspoons dried basil leaves
2/3 Cup mayonnaise
1 Garlic clove, pressed (if you don't have a garlic press you could use minced garlic)
4 Plum tomatoes, thinly sliced

Directions
1. Preheat oven to 375 F.
2. Sprinkle flour on the pizza dough, your roller, and the pizza pan (prevents sticking). Roll out the pizza dough on 12"x15" rectangle stone.
2. Sprinkle rolled out dough with one cup of the mozzarella cheese; set aside.
3. Grate fresh parmesan cheese and chop basil. Combine the remaining 1 cup of mozzarella cheese, Parmesan cheese, basil and mayonnaise, mix well. Press garlic over cheese mixture: mix well.
4. Arrange thinly sliced tomatoes in a single layer on the pizza dough over mozzarella cheese on pizza dough.
5. Using a small scoop, place mozzarella cheese mixture over tomatoes; spread to cover evenly.
6. Bake 15-20 minutes, or until top is golden brown and bubbly. Using a pizza cuter or knife, slice into individual square servings. Serve warm.
