Yes, the universal term "pigs in a blanket" can be made kosher. I use kosher sausage, frankfurters, or hotdogs and although there is no pork, people still call them by their common name. Don't worry, no pork here.
Whether its game night, movie night, or an elegant party, homemade pigs in a blanket will be a super big hit. Everyone loves pigs in a blanket. No matter what type of party I am cooking for, hosts and guests request them every time. My version are quite extraordinary because I brush the puff pastry with barbeque sauce and homemade honey mustard sauce.
Also, I use lots of different kinds of hot dogs, regular beef frankfurters for kids, and flavored sausage or kielbasa for adults. Check your supermarket for great brands and flavors and try them all. Don’t forget to serve these with awesome dipping sauces, like flavored mayonnaise or duck sauce. My favorites are homemade honey mustard  (check out the video  on how to make it!) and Sweet and Zesty Ketchup (that video and recipe are coming soon!)
2 sheets puff pastry
1 package hot dogs, kielbasa, or Italian sausage (kosher all beef, turkey, or chicken, no pork here)
Honey mustard sauce
Unfold puff pastry and gently roll it out a little. Cut it into 4 pieces.
Spread a small amount about a teaspoon of honey mustard and barbeque sauce on the puff pastry, leaving an edge on all sides without sauce (if you use too much here it gets too soggy). You can use any sauce that you like, smoky mayonnaise, spicy mustard, s’riachi or nothing if you like them plain.
Place a hot dog at the end closest to you. Fold in the sides and gently roll it up. Roll up the others until you have used all the puff pastry. Refrigerate for about 15 minutes.
Preheat the oven to 375 degrees.
Take the hot dogs out of the refrigerator. With a sharp knife, slice them in about 1-inch thick pieces. Place them 2-inches apart on a parchment or silpat lined baking sheet. Bake for 25-35 minutes or until the pastry is puffy, and lightly browned. Serve with honey-mustard dipping sauce and Sweet and Zesty Ketchup.
