Add olive oil, butter, and onions to a small sautÃ© pan and cook until soft, about 7 minutes. Add mushrooms and Marsala wine. Stir in 2 Tablespoons mustard, and salt. Remove from heat and set aside until ready to assemble sandwiches. Preheat a Panini grill pan. Set out the sourdough bread on a cutting board. Spread honey mustard on one side and mayonnaise on the other side of bread. Place the sharp cheddar on one side of each sandwich and Toscano Pepper Cheese on the other. Pile 4-5 slices of roast beef on half of each sandwich, followed by grilled onions. Place top on each sandwich and brush each side with olive oil. Grill sandwiches on Panini grill until crispy and serve.
If you are unable to find the Toscano Pepper Cheese, the sharp cheddar can be substituted. I found the Toscano Pepper Cheese at Trader JoeÂ’s.
