The selection of pastries includes picnic favourites, such as sausage rolls, sausage, pork pies and Scotch eggs.
More products are to be introduced in the coming months as part of the re-launch. These products include pizzas and other fresh produce.
The company’s pasty sales are currently up 3.8% year-on-year, and its pastry sales are up 18.9%, as reported by The Grocer.
Ian Bishop, Nisa marketing director, said: “We have improved the recipe on every product to offer great quality and value. We hope the heritage range will quickly become a firm favourite.”
