Mushroom Cheesesteak

Ingredients

• 2 Amoroso's rolls
• 3 large portobello mushrooms (Use the steaming or frying preparation method described in the instructions.)
• 1 white or Vidalia onion (Slice into 1/4-inch half moons.)
• 6 Cooper Cheese (The source specifies 6–8 slices; the cheese is also described as Cooper Sharp cheese in the method.)
• neutral oil (Canola, avocado, or vegetable oil; use as needed for cooking.)
• salt and pepper (To taste; use a pinch of salt with the onions and additional salt and pepper with the mushrooms.)

Steps

1. 1

   Prepare the portobello mushrooms using one of the two source-provided options. For the preferred steam method, steam the whole mushroom caps until softened, let them cool slightly, and slice them thinly.

2. 2

   Alternatively, for the fry method, slice the mushrooms thinly first, then fry them in neutral oil until browned and tender.

3. 3

   Slice the onion into 1/4-inch half moons.

4. 4

   Heat neutral oil in a skillet over medium-low heat.

5. 5

   Add the sliced onions and a pinch of salt to the skillet.

6. 6

   Cook the onions slowly, stirring occasionally, until they are deeply golden and caramelized.

7. 7

   Add the prepared mushrooms to the skillet with the caramelized onions.

8. 8

   Season the mushrooms with salt and pepper.

9. 9

   Cook until the mushrooms are tender and slightly browned.

10. 10

    Layer the Cooper Sharp cheese directly over the mushrooms and onions.

11. 11

    Let the cheese begin melting, then toss and mix the mushrooms, onions, and cheese together once the cheese has softened.

12. 12

    Toast the Amoroso's rolls until they are lightly crisp on the outside but still soft inside.

13. 13

    Load the hot mushroom-and-cheese mixture into the toasted rolls.

14. 14

    Serve immediately.

Notes

The source provides two mushroom preparation options, with steaming preferred for a tender texture. The source does not specify steaming, frying, or toasting times, nor a precise amount of oil.
