To start healthy pigs in a blanket, preheat oven to 400-425º. Cut Cali’flour crust or flatbread in half. Add a light coating of mustard. Place one hot dog at the corner of the crust closest to you. Carefully roll the crust around the hot dog (use a toothpick if needed to keep anchored). Place the prepared hot dog seam-side down onto a cooking sheet lined with parchment paper or vented pizza screen. Repeat to make a second hot dog. Bake for about 10 minutes, until lightly browned. Remove from oven, let rest, and then serve with desired spread like Primal Kitchen's Unsweetened Ketchup. Serve and enjoy!
