Place all ingredients, except prosciutto, in a bowl. Toss to combine. Cover and refrigerate for at least 30 minutes.
Preheat oven broiler.
Tear prosciutto into pieces big enough to wrap around artichokes. Place wrapped artichokes on foil lined baking sheet. Broil for 3 - 5 minutes or until warmed through and prosciutto is slightly crispy.
Skewer with toothpicks, if desired. Serve.
Notes
If you cannot find frozen artichoke hearts, you can use canned. However, omit the additional salt. Frozen artichokes generally don't have salt while canned artichokes are in a salty brine which makes the final dish much saltier. To make in advance, simply make to the point of broiling and refrigerate until ready. You can serve these without broiling if you'd prefer to serve a cold appetizer. I like the crispiness of the prosciutto but both ways are great! Nutrition information for estimation purposes only.
