Quick and Delicious Garlic Bread Subs

Good morning!  This is just such a perfect day!  The weather is wonderful and my family is happy. What more could you ask for?  I hope your day started out just like mine!
I am going through all of my recipes and making my menu plan and grocery list.  I asked my husband what he would like on the menu this week.  Luckily he said my garlic bread subs!  So easy and quick to prepare.  Here is the recipe......

Garlic Bread Subs

1 loaf of garlic bread from freezer or fresh
1 pkg of fresh mushrooms, sliced
1 lg. onion, sliced
1 garlic clove, minced
1 Tbsp. of butter
1 1b. roast beef from deli counter
6-8 slices of provolone, or your cheese preference

Preheat oven to 400.
Bake bread for about 8 minutes.
Saute mushrooms, garlic and onions in your butter until nice and soft.
Take bread out of oven and on each half press your mixture on top.  This is an open faced sandwich.  Now put your slices of meat and then top with your slices of cheese.  We like roast beef and provolone, but use your families favorites.  Now put it back in the oven until the cheese is melted and everything is nice and toasty.  Slice and enjoy.  Everyone in my family loves this.  For Roman I will just make a little section without the mushrooms.  This last time I used the garlic toasts in the freezer.  It worked good too.
