Heinz BreadNButter Sandwich Slices Pickles feature crunchy pickled cucumber chips soaked in vinegar, which infuses them with a delicious, tangy flavor. With added chunks of onion and a blend of spices, these pickles will add a completely new dimension of flavor to your favorite sandwich. The simple addition of a pickle can work wonders on your hamburger or other sandwich. Add a layer of slices just above the patty or other protein to create a gourmet meal. The juices from the pickle absorb into the patty and create a wholesome experience that is both crunchy and tangy.
