I use to work at Burger Pit on Monterey HWY in San Jose as a teen and that is where I got the idea of my Steak Sandwich.
I just cook up thin (not too thin) steak and add it to a roll that has been under the broiler with garlic butter on it. I do not add any Mayo or anything like that, my husband does sometimes. I just add the lettuce and tomatoes.
I melt butter with chopped up garlic and some garlic powder and toast them under the broiler.
These are great!
