We've taken the key ingredients of a Philly cheesesteak--onions, peppers, thinly sliced beef and provolone cheese--and piled them into portobello mushroom caps to make a meaty and satisfying low-carb main dish.
Tip: To prepare portobello mushroom caps, gently twist off the stems of whole portobellos. Using a spoon, scrape off the brown gills from the underside of the mushroom caps. If you prefer, purchase portobello mushroom caps, rather than whole mushrooms.
