I usually fix my Italian Sausage on the grill when my son invites his friends over for a cook out. They tell me it's like eating Pizza on a Bun. Well back in 2003 I sent my recipe Johnsonville for review and ended up with $20.00 worth of coupons for their product and a nice letter thanking me for my recipe. Seems they liked it as well. I know it to be kid friendly, family friendly and company friendly so I hope you enjoy it as well. You can serve a 3-Bean Salad, Potato Salad, or Pasta Salad with this as well. It's what ever you like. Toppings can vary depending on your tastes.
Grill your sausage till it's nice and brown. While your sausage is cooking on the grill you are going to slice your onions thin and place in a saute pan with your sliced mushrooms. In another small pan you should be heating up your favorite sauce. While all this is going on put your hot dog buns on a cookie sheet and open them up.
When the sausage comes off the grill, place them on the buns, top with sauce, onions, mushrooms, and then cheese. Place in oven about 3-5 minutes. Just to let the buns warm and the cheese melt. It's like pizza on a bun and the kids will love it. Serve with your favorite salad.
