A great deep dish pizza that I have made for years. Leftovers are good reheated or cold. Kids might not like it because of the spinach & mushrooms. This is a not a quick recipe. It's not complicated but has many steps. It's worth the work. Once you have the basic recipe down, you can play with the ingredients. I often cut back on the salt in the dough & add garlic salt, basil & oregano. I also use the dough recipe for a hand tossed thinner crust pizza. I usually save this for a slow weekend. To speed things up I use pre-shredded cheese and bulk Italian sausage when I can find it. If you don't like whole wheat in your crust, just replace with white flour. The crust is pretty crunchy.
