This recipe sounds like it could be be SBD friendly:

Mushroom Pizza

4 portobello mushroom caps
spaghetti sauce
favorite pizza toppings

1. Wash mushroom caps and let dry.
2. Spray mushroom caps and heating tray with cooking spray.
3. Place on tray with open end up.
4. Layer sauce on cap and place your favorite toppings.
5. Bake in preheated oven at 350 for 10-15 minutes.

My ideas for pizza toppings: LF/FF mozzarella cheese, parmesan cheese, canadian bacon, olives, tomatoes, broccoli, extra lean ground beef, soy crumbles, etc.

Nummy! I'll try it as soon as I get to a store with Portobellos. Thanks for posting this. I think there is a similar recipe in the book.
