In a large skillet, heat olive oil with onions. You want to sautee them on medium low heat until they become soft and translucent. I choose to do sliced onion, but you can totally dice them up as well!

Once the onions have sauteed add in the mushrooms. Be sure to season both the onions and mushrooms with salt. This helps to bring the moisture out of them and become soft. Not to mention, they need the flavor.

Once the mushrooms have broken down and soft (they will turn a darker color) add in the shaved steak along with 2-3 tablespoons of your favorite steak seasoning.

Cook the steak until it’s cooked through, about 8-10 minutes. Make sure to toss the steak around in the onions and mushrooms.

Grab your hoagie buns and place mayo on both sides of the bread. Put as much or as little on as you’d like.

Place steak on top of the bottom roll and the provolone cheese on top. Place in an air fryer on 350° (or the oven) to toast the bread and melt the cheese. In the air fryer it’s about 1-2 minutes and for the oven expect 5-8 minutes.

Serve with homemade french fries, chips or if on a keto or low carb diet I serve mine over a bed of lettuce!
