Preheat oven to 350 degrees. Line a large sheet pan with parchment. Place a 4 inch bowl in the center of covered sheet pan.
On a clean work surface unroll crescent dough and separate triangles. Place mustard into a small bowl and using a pastry brush cover lightly each triangle of dough.
Using a pizza cutter, cut each triangle of dough into 3 pieces lengthwise.
Place one smokie on large end of each 3rd of the dough and roll to the tip. Place seam side down on sheet pan 1 inch from edge of bowl. Continue placing the rolled smokies onto sheet pan in a circle shape to create a wreath.
Beat egg and 1 TBS water in a small bowl until frothy. Baste the rolled crescents. Sprinkle poppy, sesame, or everything but the bagel seeds on the rolled crescents.
Bake in preheated oven for 12-15 minutes until golden brown.
Mix sauce ingredients (mayonnaise, sour cream, and mustard) together. Pour mixture into the 4 inch bowl used earlier.
Remove pigs in a blanket from oven, let rest for 5 minutes. Place the parchment on a serving platter or large plate. Slide parchment out from the pigs in a blanket ring. Place bowl of dipping sauce in center.
Decorate with parsley, thyme, or rosemary to give a Christmas feel. Place halved cherry tomatoes around the wreath. Enjoy.
