This is my second post today but I actually made this 2 weeks ago, but just didn't post it.
This is a simple recipe. Make up 1/2 a batch of the
healthier meatball mixture I posted previously. Take 1 lb of baby portabella mushrooms and remove the stems so there is a hollow place. Stuff each mushroom with some of the meatball mixture. Place on a baking sheet and bake at 350 degrees (F) for 15 minutes.
