1 sandwich (280 g) has about 600 calories.
Why estimates miss: Reuben Sandwich is a multi-ingredient dish. Corned beef, Swiss, and Russian dressing make this a rich choice, so halve it if sharing. Generic calorie apps undercount the hidden oil, sauce and portion — CalDesk AI's photo estimate is tuned to catch exactly this.
