How to make this tomato pie recipe
Prepare the ingredients: clean and dry to tomatoes, chop the onions and garlic, grate the mozzarella cheese, and measure the ricotta cheese.
Preheat the oven to 375 degrees F, and coat a pie pan with oil.
Step 1. Slice the tomatoes
Use a sharp knife to slice tomatoes. Arrange them onto a paper towel for a few minutes to absorb excess moisture.

Heat olive oil in a skillet over medium-high heat. Once the oil is hot, reduce to medium heat. Add the onions and garlic. Cook until they begin to soften and remove them from the heat.
Step 3. Combine filling ingredients
Whisk the eggs together in a small mixing bowl and whisk ricotta cheese into the eggs.
Step 4. Add the garlic & onions
Stir the cooked garlic and onions into the mixing bowl.
