To make: Let your Italian Spinach Crust thaw for 10 minutes. While the crust thaws, mix together cooked ground beef and marinara. Lightly coat a pan in oil of choice and cook thawed crust on med/high heat for 2-3 minutes on each side. Add small layer of mozzarella & parmesan cheese to half the crust. Add layer of meat/marinara mixture. Top with a final layer of cheese and fold over. Cook on both sides until desired crispness.
Tip: Try using Rao's homemade marinara sauce
