Mushroom, Onion, and Tomato Pizza

On Thursday I made up my own pizza, and it worked pretty well. The only problem was that I used store-bought dough and it didn't stretch very well and was pretty thick. The pizza topping I made was delicious, though. I used:
1 portobello mushroom, sliced thin
4 regular white mushrooms, chopped
2 garlic cloves, minced
1/2 a white onion, sliced thin
1 tomato, chopped
salt and fresh-ground pepper to taste
1/2 cup packaged grated mozzarella-provolone blend
1 ball of pre-made dough
1) Add some olive oil to a skillet on medium-high heat. Add the garlic and onion and cook until the onion is starting to soften.
2) Add the mushrooms and some salt and pepper and cook until the mushrooms are soft.
3) Add the chopped tomato and cook until it's warm, basically.
4) Put all of this on the pizza dough, hopefully stretched better than mine was and top with the cheese. Bake until the cheese is melted and bubbly and the crust is golden brown.
Eat.
