My compadres make home made pizza's a lot at our cabin or in FL and they are awesome. Going to do it myself since first job I had was making pizza's at Ponticello's resteraunt in North STL and it's really easy to do. especially when simply buy the crust.

BUT even easier? is buy any decent frozen deluxe pizza and dump a lot of mozzarella cheese on top and add some ingredients INCLUDING MUSHROOMS! BTW they don't have any taste but simply absorb flavors around them and I have grown to love them and onions on pizza. We usually Cut them in HALF as two of us seniors don't eat that much and that's more than enough for us and then you have the other half ready to go.
