Cut the stem ends off the beans.
Add 1 tablespoon salt to a pot of boiling water and then add the beans.
Cook the beans until they are crisp tender; approximately 5 minutes.
Meanwhile, prepare an ice bath for the beans; fill a large bowl with ice water, leaving enough room for the beans.
When the beans are cooked, drain them in a colander, then immediately place them in the ice bath to cool completely; drain the beans in the colander again and set aside.
Place green beans in a container.
Add ½ of the bottle of the Zesty Italian dressing; marinate overnight.
When ready to serve, pre-heat oven to 350°F.
Assemble the bundles; lay approximately 10 green beans, all facing the same direction, into a bundle and place in the center of the bacon or prosciutto; secure with a toothpick, if necessary; repeat; set bundles aside.
Place in baking dish and pour remainder of Zesty Italian dressing over the top.
Bake covered, for about 35 to 40 minutes
If using prosciutto, reduce baking time to about 10 – 15 minutes or until prosciutto is starting to get crispy.
