Easy Peasy Casserole
This is an easy dish to make with lots of yummy pizza flavor. Kids and adults will love this dinner. You can adapt it to your preferences by including more “toppings” like mushrooms and olives or just keep it simple with only pepperoni. It’s a cinch to cut this recipe in half or double it to serve a crowd, depending on how many people you’re looking to serve.

Delicious recipe! I used whole grain rotini, extra lean hamburger, turkey pepperoni and added 1/2 chopped zucchini. Leftovers were just as good with a splash of water when warming up. Thank you!
I love those ideas Kathy! thanks for the 5 stars 🙂
