Season steak with spice and set aside.
Chop garlic and add 1/4 cup of butter and chopped parsley.Microwave for 1 minute and let rest.
Add green pepper, onion and mushrooms to frying pan - dot with butter and add some salt and pepper. Cook over med/low heat until soft.
Halve the kaiser rolls and butter with the garlic mixture on both sides. Add slice of mozzarella/swiss (sometimes I combine) to bottom half of rolls.
Sprinkle a second frying pan (or grill) with olive oil and when ready, sear the seasoned steaks on both sides. Turn off heat and cover with tin foil tent for at least 5 minutes.
Preheat oven to 350 degrees.
Assemble sandwiches by adding steak on top of cheese, add mushroom/green pepper/onion mixture and close sandwich with top of roll.
Wrap in tin foil and heat in oven for 10 minutes.
Remove and let then cool a bit -- then enjoy!
