Spinach and Cheese Pizza

Preheat oven to 450 degrees. Oil a cookie sheet. Roll pizza dough until ¼ to 1/8” thick. Place dough on oiled cookie sheet.  Put pizza dough in the oven for 3 (thin crust) to 7 (thick crust) minutes. Remove partially cooked crust front oven and rub with 1 Tbs butter.  Rinse spinach with water and drain.  Leave slightly wet, so that it steams as it cooks in the oven.  Place spinach on partially cooked crust.  Cover with grated and crumbled cheese.  Put pizza in oven fro 10-15 minutes, until crust begins to look crispy and cheese begins to brown.  Remove from oven and slice.
