Preheat a flat top or large skillet to 385 degrees F (medium heat).
Saute mushrooms with some oil, then add some butter and salt. Open hogie rolls slightly by hand. Squirt blended oil in a separate portion of the flat top and add onions. Place rib eye steak on the onions and add butter. Cover with lid and cook until it looks cooked on top but is still pink inside, 2 to 3 minutes. Mix steak and onions together until cooked. Apply salt and a little butter. It should be tender and moist. Add cheese and melt. Remove steak with spatula and place in rolls. Cut in half.
