Philly Cheesesteak Stuffed Portobello

Steak and mushrooms work so well together, so why not make stuff them with this cheesy deliciousness! I love a good Cheesesteak sandwich, but the average Cheesesteak contains roughly 900 calories and 40 grams of fat which is fine for an occasional indulgence, but not something I would want to eat everyday. This healthier version skips the bread and stuffs all the cheesy goodness into a Portobello mushroom.

This lighter version is still decadent, yet has plenty of vegetables to balance it out. I’m sure this would also be great with chicken if you prefer. Serve it with a big salad and call it a meal!
