Found this one on Allrecipes.com and tweaked the ingredients just a bit to fit the picky Italian DH. Ground sausage as opposed to ground beef gives the dish much more flavor. Do ahead tip would be to stuff the shells the night before, place in red sauce, refrigerate, and then make the white sauce just prior to cooking. Watch the amount of chicken bouillon as it can make the white sauce way too salty. Serve with some garlic stuffed/sauteed artichokes (Recipe #61210) and a small garden salad.
