My Best Tips

Let it rest after baking it slices better. Add fresh herbs on top for color and flavor. Want it vegetarian? Skip sausage add mushrooms and tomatoes. Play with different cheeses and spices make it your own.

Keep It Fresh

Leftovers stay good in the fridge for three days. Warm it covered in the oven or microwave single servings. Freezes beautifully for three months just thaw before reheating.
