Walkers crisps & Heinz Sandwiches

I think we're all guilty of putting crisps in our sandwiches. Occasionally! Now the kind people at Walkers crisps have produced a new range of sandwich-flavour crisps that saves us the bother. What's more, they have collaborated with Heinz, so that each flavour incorporates a sauce from Heinz. They are Bacon and Ketchup; Cheese, Cucumber and Salad Cream; Roast Chicken and Mayonnaise; Ham and Mustard; Toasted Cheese and Lea & Perrins Worcester Sauce; and Sausage and HP Sauce. Genius!
