Crunchy, thinly sliced potato chips, from German spuds roasted in sunflower oil and lightly seasoned with chili pepper. Eat them right out of the bag or add to salads or canned herring. Goes well with German beer.

From Funny Frisch (Internsnack), the iconic savory snack brand from Cologne (North Rhine Westphalia). Their famous advertising slogan: "Knusper, knabber, knackig, frisch" (try to say that 10 times very fast). :)
