Let dough rise in a warm place until soft and warm, 1 to 2 hours.
Heat oil in a large deep skillet or sauté pan over medium heat. Add onion; cook 10 minutes or until beginning to brown, stirring occasionally.
Add sliced mushrooms and continue cooking 8 to10 minutes until mushroom liquid is evaporated. Add wine; simmer until almost all liquid is absorbed, 10 to 12 minutes. Stir in sun-dried tomatoes and olives. Add salt, pepper and hot pepper flakes to taste if desired; set aside.
Grease a 12-inch pizza pan lightly with shortening. Place warm pizza dough in center of pan. Gently stretch and press to fit the pan and push up a rim of dough around the edges of pan.
Spread pesto over crust if desired. Top dough with onion and mushroom mixture. Sprinkle Blue cheese and shredded cheese evenly over pizza. Brush additional olive oil over edges of dough if desired.
Bake in a preheated 400°F oven 20 to 22 minutes or until the crust is light golden brown and cheese is melted and deep golden brown. (Baking the pizza on the bottom rack for 10 minutes and top rack for 10 minutes creates the perfect brownness of crust and topping.)
