Sure, these Beef Wellington Burgers aren't meant to be handheld but they do welcome a side of fries with open arms! A puff pastry square is layered with salad greens and cheeseburger spiked with horseradish and Dijon mustard before being topped with mushrooms, tomato, french fried onions and a horseradish Dijion mayonnaise. What do you serve your family for Christmas dinner?
