Preheat oven to 400 degrees F.

Rough chop the mushrooms stems and dice your onion.

Heat olive oil in a pan and saute onions with salt until they start to soften. Add mushrooms and continue to saute until cooked through. Add mushroom stems and keep cooking until cooked through.

Cool mushroom and onion mixture and combine with pesto hummus and Panko bread crumbs.

Fill up the mushrooms with the mixture and top with fresh Parma- or not to make it vegan! Put them on a foil lined sheet pan.

Cook for 20 minutes or until mushrooms are cooked through.
