Plant-Forward Perfect for the Grill: Portabella Mushroom Sandwich

SALT LAKE CITY – Tired of hot dogs and hamburgers on the grill? A portabella mushroom is a great edgy and hearty option for a backyard barbecue.

“Portabella mushroom has a nice, meaty texture and is often used in place of steak or other meats in vegan or vegetarian dishes,” said Josh Broadbent, executive sous chef of Intermountain Healthcare. “Just be sure to remove the gills with a spoon before putting the mushroom on the grill. Otherwise, it will stick to the grill and have a muddy flavor.

In addition to being low in calories and fat, mushrooms provide fiber and various nutrients to the diet. Most notably, mushrooms contain a wide range of phytonutrients which, in animal studies, have been shown to protect against certain cancers and inflammations in the body.

The Portabella Mushroom Sandwich is topped with grilled red pepper, provolone cheese, and balsamic aioli for a rich, smoky flavor, and served on whole wheat ciabatta bread.

Here is the recipe:
