> the Norwegian sandwich definitely has less fat (less cheese, less calories in the butter than mayo or other sauce, less fatty meats) Butter is much higher in saturated fat and calories than mayo, and you're putting butter on 3 slices whereas you usually only but mayo on one (per the article). One tablespoon of butter is 100 calories and 7 grams of saturated fat, one tablespoon of mayo has 60 calories and 1.5 grams of saturated fat. If I look at the nutritional information for Kalles Kavier (which someone suggested as a topping), it seems to also be pretty high in calories with a lot coming from extra carbs (sugar).
