Spinach Dip Pull-Apart Christmas Tree!! You will be the star of your Christmas party when your guests see and taste this display! And, it is actually an easy finger food that looks a lot more complex than it is. It starts with a store-bought puff pastry sheet that is topped with an easy spinach artichoke dip mixture. Then, after topping the dip with another layer of dough, it’s all about cutting and twisting. And, don’t forget about the garlic butter for added flavor.
