If you add bacon to this recipe it will up the protein.
These sound really good to me for some reason today!

I very rarely follow a recipe verbatim. I tend to use recipe as a concept and a guide for ratios, cooking time, temperature, etc. everything about a recipe is open to interpretation. Except for baking recipes if I mess with it I will mess it up.
so by all means try it. I think zucchini would cook more like the mushroom.
