To make it easy, purchase prepared refrigerated pizza dough or use your own favorite pizza dough recipe. You can cut this complete recipe in half to make 4 turnovers. Cooking the spinach in the microwave firstly is only optional, I prefer to use cooked spinach rather than raw, cooking it first will mellow out the strong taste of the spinach, if you do not mind a strong taste then omit this step. I have made this many times using puff pastry in place of the pizza dough!
