Ingredients

Sandwiches

1 Tablespoon butter
8 ounces sliced mushrooms
1/2 vidalia onion sliced
1/4 cup Guinness beer
1 package sandwich rolls I used King's Hawaiian Savory Butter Rolls
3/4 pound sliced roast beef
6 slices Swiss cheese

Guinness Glaze

1 bottle Guinness beer
1 stick butter
1/4 cup brown sugar
1 Tablespoon dried mustard
1 teaspoon onion powder
2 cloves garlic minced

Instructions

In a medium skillet, melt butter over medium-high heat. Add mushrooms, onions and 1/4 c. Guinness and saute until liquid is absorbed.
Prepare glaze by combining all ingredients in a medium saucepan. Bring mixture to a boil, then lower heat slightly and cook until thickened. (*Mixture should be reduced by at least half - when in doubt, reduce it a little more!)
Assemble sandwiches by slicing rolls in half, then filling with roast beef, sautéed mushrooms & onions, and swiss cheese.
Pour glaze evenly over sandwiches.
Bake, uncovered, at 350 degrees for 30 minutes.
