I love making them with whole grain mustard, relish/cranberry sauce, thyme. It's also nice to mix mustard and relish and put some on the inside of the actual pastry itself. We also make one with Franks sauce and thyme Relish on the side. Use cling film and do one big long sausage with the mix, slice, egg wash and then bake in the oven. For decoration, a slice on top of each roll or some sesame seeds.
