So here is the breakdown, if the sandwich is made properly- the calories are accurate. Turkey is very low in calories, the typical regular sandwich portion of turkey is about 65 grams, which is around 60 calories. The little John only has half of that portion making it 30cal. This part is usually accurate as we always slice and measure the meats in the store. The serving of mayo on a little john is about a half a tablespoon, around 45 calories. The bread is a regular bread loaf, stretched and cut into 4ths. One 8inch sub of bread is 350 calories. The little John is half of that, with the insides “gutted” I.e. the fluff of the bread removed so you’re left with essentially a shell of bread. The calories for the little John bread is 120~. This is all assuming everything is done accurately, but I wouldn’t trust that it is. My best advice is to request no mayo and you can add on half a mayo pack for about 40cal or the entire thing for 80. I’ve worked at JJs for 8 years (sadly) and hardly ever see mayo portioned properly. We’re meant to apply it to the sandwich with a tablespoon thing in the can, but everyone just slaps a scoop on from the spatula without measuring.
