Save: 100 calories
There’s a reason cauliflower has a reputation as the skinny “starch.” Boasting only 29 calories per cup (compared to 130 calories in a medium potato), it also delivers almost a day’s worth of vitamin C. It’s a versatile vegetable that’s delicious mashed, blended into a “creamy” soup or roasted. Celery root is another good swap for mashed potatoes—just replace some of the potatoes with boiled celery root.
