Step 1

Brown the ground beef and ground sausage in a large skillet over medium-high heat.  When it is about halfway through the browning process toss in the butter, mushrooms, and onion.  Cook until the meat and mushrooms are browned and the onions are soft.

Step 2

Turn the heat to medium low.  Add the garlic and marjoram cooking for 1 minute while stirring constantly.  Stir in the marinara. Season with kosher salt and fresh ground black pepper. Continue simmering for about 7-10 minutes.

Step 3

Meanwhile split and toast the English muffins on a baking sheet covered with aluminum foil under the broiler.  Divide the meat mixture evenly over the toasted muffins.  Top with the diced pepperoni and sprinkle with the mozzarella; dividing evenly.  Place under the broiler for about 2-3 minutes or until the cheese is melted.
