Notes

Make this recipe ahead of time! Prepare and bake as the recipe states. When it's had time to cool off after coming out of the oven, cover with foil, and stick it in the fridge for up to 3 days. When you're ready to eat it, pull it out of the fridge and pop that bad boy straight in the oven to bake at 350°F for 30-45 minutes or until heated through.
