I loosely followed the recipe as I only needed 2 servings. I added a chopped yellow squash and a chopped zucchini for more veggies. I used low fat basil-tomato instead of Parmesan cheese--it came out beautifully! We loved it! Very tasty, filling and low cal/fat. Will definitely make it again. Note: the veggie filling would also make a wonderful omelet.

Cook and a half

Made this for the family as we are trying to have a meatless meal introduced into our diet. Unfortunately none of my family enjoyed this. There was a definite lack in cohesive flavor. The spinach, tomato etc completely turned out to not be a flavorful combination. The Portobella taste was lost to the funky taste and texture of the filling. Unfortunately will not be trying again. * Also, the avocado did nothing to help the taste. Sorry for the not so great review. Thank you for the recipe.


Add a little goat cheese in the spinach mixture for a tasty, protein replacement meal.
