This is one of my favorite dishes to make for company. 
Use your fingers to separate the skin from the breasts of the hens – be careful inserting the prosciutto under the skin.  I serve this with long grain wild rice, and usually oven roasted green beans or asparagus, and a nice gorgonzola pear salad.  To oven roast either veggie, brush with olive oil, sprinkle with fresh ground sea salt and powdered garlic, and bake at 400 for about 15 minutes ( in this case – put in with the hens at 425 for about 12 minutes).  Warm the cream cheese up slightly before mixing herbs in – makes it a bit easier.   I  like to serve this meal with a nice Fume Blanc by Dry Creak Vineyards – an oaked version of Sauvignon Blanc – very mild, and crisp enough to bring out the fatty taste of the birds!  About $13 a bottle.
The nice thing about this meal, is the birds can be prepared the night before, and refridgerated.  Total cook time for everything is 40 minutes.  I usually serve an appetizer, then pre heat the oven.  Once the birds are in, about 5 minutes after they are turned for the first time,  I make sure everyone is heading to the table.  Plate the birds with the rice and veggie, add the salad in separate bowls, and you are good to go – a relatively minor time in the kitchen for a totally gourmet meal for company!  One hen per person – adjust to head count.
