Three complete Krystal meals under 600 calories

Under 600, the most-protein meal is built on the Chipotle Patty Melt (limited time) (520 cal), which leaves 80 calories for its sides and drink. One meal-sized entrée, up to two different sides and a drink — the MinMax app's meal and the best under the cap, drink included (water only where no published drink fits; the lightest meal takes a zero-calorie drink, or water). The lightest meal is unchanged from under 500; the others use the extra 100 calories.
