Coat a hot flat-top grill or frying pan on high heat with olive oil. Add mushrooms, onions and bell pepper and cook until vegetables are softened, about 5 minutes. Season with salt and pepper.
Add rib eye and continue to cook until meat is cooked through, about 3 minutes.
Remove from heat and transfer to a large non-plastic bowl. Allow to cool for 15 minutes.
Add shredded cheese to bowl and mix together until you have a homogenous mixture.
Fill a small bowl with water. Take one eggroll wrapper and place it in front of you with a corner facing you. Spread 1/4 cup of the meat and cheese mixture across the center of the wrapper, going from the left to the right corner. Fold the left and right corners over the filling, then pick up the corner closest to you and fold over the filling. Roll up the eggroll, sealing shut with some water. Assemble eggrolls using the remaining wrappers and filling in the same manner.
Preheat oil in a deep-fryer to 350 degrees F. Fry eggrolls, turning once to achieve consistent browning, about 2 minutes total. Drain on paper towels.
Cut eggrolls in half and place on a bed of shredded cabbage. Serve with your favorite Dipping Sauce.
