Portabella Mushroom Burgers

READY IN: 35mins
Recipe by Mimi in Maine

This is a healthy switch from the traditional burger. These are really soooo good. There are three steps before the grilling but not hard steps.

Everyone loved this, even the so-called mushroom haters were happy. Great source of potassium (more than bananas which you need more in the summertime, or for those still growing (growing pains are a sign of not enough potassium)! I would like to try reducing the oil in the marinade next time. Also wood chips in the grill are important, the outside of the mushroom really takes on that flavor.
