Bring the Hoagie rolls and slice them using a sharp knife.
Then bring the onions and dice them. Also, slice the beef at the same time.
Take a small-sized bowl and add the melted butter to it. Add the crushed garlic to it.
Brush the sliced rolls with the garlic and butter spread.
Fry the roll buns on the stovetop until they are golden brown.
Bring the cooking pan and pour oil into it. Add the diced onions and stir fry these onions until softened.
Add more oil and then add the steak into the heated oil. Sprinkle the seasonings and fry until browned.
Then you have to cut the steak into four portions to fill up the sandwich. Add cheese so that the cheese can melt.
Now bring the rolls spread mayo over them, and fill the steak and cheese mixture over it. Cover the top with the other half.
Serve your Sandwich with delicious dips.
