Stretch out your dough on to a pizza stone or into a pizza pan. Pierce the dough with a fork, drizzle the dough with a touch of extra-virgin olive oil and sprinkle it with oregano. Bake dough 10 minutes.
While the pizza dough bakes, heat a tablespoon of extra-virgin olive oil (1 turn of the pan) in a large nonstick skillet over medium to medium-high heat. Add butter to the warm oil, then the chicken or turkey. Lightly brown the meat 3 to 4 minutes, then add the chopped red onion, garlic and grill seasoning and cook 5 minutes more. Wring the defrosted spinach dry by twisting it in a clean kitchen towel over your sink. Add it to the meat, separating it with your fingers. Add in feta crumbles.
Once the pizza has cooked 10 minutes, remove dough and top evenly with meat and spinach mixture. Cover the pizza with shredded mozzarella or provolone, roasted peppers and olives. Bake pizza another 13 to 15 minutes until cheese is bubbly and crust is crisp.
Remove pizza from oven, top with chopped parsley or arugula, cucumbers and hot peppers and serve.
