Get yourself a bottle of spiedie sauce (either Lupo's or Salamida's) and marinate chunks of your favorite meat in it, the longer the soak the better. You can either then skewer the meat or cook the loose pieces, grill works best for flavor, but cooked in a hot cast iron skillet works. Take a piece of sliced italian bread and put your finished spiedies on, slice of cheese optional. Eat and enjoy.

P.S. If you wanted a recipe to make your own marinade here's one:
1/2 cup olive oil
1/2 cup Red wine vinegar
2 tsp. sugar
garlic minced, as much as you like
2 tsp. Dijon
1 tsp. salt
1 tsp. pepper
1 tsp. dried tarragon
1 tsp. dried oregano
1 tsp. dried basil
This makes enough marinade for about 2 pounds of meat, maybe more.
