This is a great snack or lunch or dinner or anytime at all! I ate both of these bad boys and it was only 257 calories. Sooooo good. It is really simple. Just get a portobello mushroom cap and scrape the gills and remove the stem. Then add 1/4 cup of sauce and 1/4 cup of cheese. I also added some roasted red peppers. I put them into a 350 degree oven for about 15 minutes. Delish!
