Mama Mia Vegetable Pie

My husband did Weight Watchers online a few year ago.  That's when we came across this recipe.  I have to admit that I am a carnivore and love my meat in most dishes.  But with this one, I instantly fell in love and I do not miss the meat at all.  We absolutely love this dish!  It is super easy to make, healthy and delicious!  I adapted it a little by adding more veggies and  cheese, of course; but it's still within the healthy range.:)  Enjoy!

 Ingredients:
-1 Tbs vegetable oil
-1 medium bell pepper, chopped (or you can use frozen)
-1 onion, chopped (or frozen)
