Upside-Down Chicken/Broccoli Pizza

• 3 T. olive oil
• 1 large onion, chopped, about 1 cup
• 2 c. cubed chicken, not cooked
  
• 2 t. Italian seasoning
• ½ t. salt
• ¼ t. pepper
• 4 oz. mushrooms, optional
• 3 cups (16 oz. frozen bag) cooked broccoli, chopped
• ½ c. ranch dressing (leaving this out next time)
  
• ½ c. white Alfredo sauce (using 1 cup next time)
  
• 2 c. (8 oz) shredded mozzarella cheese
• 1 11-oz. tube refrigerated pizza dough
• 1 egg, beaten
  

~Preheat oven to 400º.
 ~If you have one, use a skillet with oven-safe handles.  Heat oil in skillet, add onions, mushrooms, seasonings, and chicken.  Cook until chicken is cooked through.
~Cook broccoli, drain.
~After chicken is cooked, stir in broccoli, ranch dressing, and Alfredo sauce.
~In oven-safe skillet, sprinkle cheese over mixture and remove from heat.  Or pour mixture into a casserole dish and sprinkle cheese on top.
~Unroll dough and lay over top of skillet or casserole dish.  Fit dough over the edge of pan and cut off corners of dough.  Create a crust by rolling any excess dough down, and then stuffing along inside the edge of pan.  (My edges that were higher browned first.)
~Brush with beaten egg and bake for 18-20 minutes.  Let rest a few minutes before serving.

I knew JohnDavid probably would not like this, so I made him one without sauce. (I cooked more of everything in the recipe)  He liked it. (ETA: not as much as I thought.  Prob just make him a pizza next time =) I topped it with the dough I cut from the edges.  His was done in 16 minutes.
The dough was much bigger than I realized, and it would easily cover a rectangular dish, with leftovers for JohnDavid's.  I still have a little in a zip-loc baggie in the fridge.  2/12/10 ETA:  I looked again at the pizza dough at the store, and saw another tube, and realized I'd gotten the thin crust -- slimmer, longer tube.

I didn't care for the slight ranch taste, and will probably use all the Alfredo mix next time.  I bought McCormick's, and it makes one cup.
