Warm a sauté pan over medium-low heat. Using a ¼ pound of each deli meat, create two stacks. Transfer those stacks to your sauté pan. Cook for 1 minute and then flip the stacks. Layer the Havarti cheese on top. Cover and let the cheese melt and the meats to warm-up.
Slice your rolls in half. Lay them in your toaster oven. Turn the toaster oven on for 30 seconds and then turn it off. You don’t want to toast the rolls, just warm them up.
Remove the rolls from the toaster oven after 2 minutes. Slather with the horseradish cream sauce, deli mustard, and sweet onion jam. I like to do this on both halves of the roll. Place the Swiss cheese on the bottom half of the roll.
Remove the meats from the sauté pan and transfer them directly on top of the Swiss cheese. The cheese will melt from the residual heat. Place the other half on-top, slice in half, and enjoy!
You can find the Sweet Onion Jam recipe here. Have your deli meats sliced to a thickness of your preference.
