Steak and Everything Sandwiches

This was pretty good, new recipe I tried. I omitted the mushrooms from my sandwich of course. And the onions. And the green peppers. No, I'm just kidding, I ate the green peppers, what do you think, I'm picky or something????

Ingredients:

1 lb deli roast beef slices, chopped
8 oz cream cheese (use 1/2 to 3/4 or desired amount- 8 oz seems to be too much!)
1 small bell pepper, chopped
1/3 red onion, chopped
¼ cup chopped mushrooms
French bread or some other long loaf of bread.
Swiss Cheese
Garlic salt

Cut bread in half in sandwich style. Butter both pieces of bread and sprinkle with garlic salt. Next layer both top and bottom with swiss cheese. Toast in oven until cheese has melted. While the bread is toasting, combine roast beef, cream cheese, bell pepper, red onion, and mushrooms in a pan and heat until cream cheese is melted. When bread and beef mixture are both finished, scoop beef mixture onto bread. Serve warm.
