Preheat the oven to 350 degrees.
Brown the meat in a skillet over medium with olive oil and add salt and pepper to taste.
Put cooked meat in a colander to drain out the liquid - very important step!
Sauté’ onions in the skillet with olive oil til translucent on medium heat.
Push cooked onions out to the edges of the pan and turn to medium/low - add a little olive oil in the center of the pan and add the fresh chopped garlic, stir for 1 minute.
Place about 10 paper towels stacked on top of each other on the counter, put the onion/garlic mixture on the paper towels. Wrap the paper towels around the onion mixture to drain out any liquid.
Cook bagged spinach in the microwave or in a stockpot until thawed and warm.
Repeat the same process with the spinach that you did with the onion mixture - squeeze out all the liquid - very important so the crust won’t get soggy.
In a large bowl mix the meat, onions and spinach.
Add parmesan cheese, whisked eggs, fresh basil, dried oregano.
Have a large baking sheet and grease with olive oil if you don’t have nonstick. Some cornmeal will prevent sticking as well. Roll out one of the packages of dough in a rectangle shape to fit the pan. Use flour on the countertop so it won't stick. It’s better to have too much than too little. You don’t want the crust to be too thick but too thin and it will tear. You can cut off the excess on the edges after you put the second piece on top.
Put filling on top of the dough in the pan getting it thick enough to cover and up to all the edges. The filling will be about 1⁄2 inch thick.
Place sliced cheese across and down over the whole pizza filling overlapping the cheese by about a 1⁄4 inch. This makes it extra cheesy.
Roll out second package of dough in the same shape and fold over once and then twice so it is easier to pick up and place on the filling. Then open up to cover all the filling. Pinch it around the edges with only about 1⁄4 inch crust because it will double in size when it cooks. You don’t want too much crust. So you will need to cut extra dough around the edges of the pan as you go around the edges.
Make slits on top in the shape of a Christmas tree for decoration and bake for approximately 30 - 40 minutes.
Remove from oven when it is golden brown and the cheese is bubbling through the slits.
