Quick, easy and healthy pizza

I want to share this quick, healthy meal tip because everyone is pressed for time these days.  I picked up a delicious whole wheat flatbread pizza crust earlier and topped it with olive oil, crushed tomatoes, baby portabella mushrooms and shredded rice "cheese".  Ten minutes later I had a hearty and healthy meal.  Simple and almost vegan (rice cheese contained casein).  Eat your heart out, literally!
