If you are hosting a holiday dinner, you will most likely end up with leftovers. Personally, I think if you are going to all the trouble to make a huge meal, there better be leftovers so you don't have to cook again for awhile! Leftovers are something even the Test Kitchen has to deal with! When Food Specialist Irene Fong was developing the Roast Turkey with Herbed Aioli for the December issue, we of course had lots of leftovers. Looking for something for lunch, I turned the leftovers into a scrumptious sandwich. So take all that leftover roast turkey from your holiday meal and turn this, Plus this, Into this! With the addition of a few strips of bacon, lettuce,  cranberry sauce and a baguette, we had an amazing sandwich, perfect for a Boxing Day lunch! To assemble this sandwich, start by cutting the baguette in half horizontally. Toast under a broiler if you want (I wanted - I love crispy baguette). Spread bottom with cranberry sauce, layer on lettuce, cold sliced leftover turkey and a few strips of crispy bacon. Slather on some (OK, alot!) of the herbed aioli on the top of the baguette, and enjoy! It was sooooo good - probably the best turkey sandwich I've ever had! Don't have leftover turkey? The sandwich is just as good with sliced deli meat! Here are more delicious ways to use up that leftover turkey. And if you like leftover turkey sandwiches, try this Turkey Club. Don't want to deal with leftovers? Make sure your bird is just the right size for the number of guests.   Photography by Ryan Brook (top); ©iStockphoto.com/Sarsmis (middle); Leah Kuhne (bottom)
