Smart swaps
- 1/4 lb ground beef patty→Grilled portobello mushroom cap
Eliminates nearly 25 g of fat per serving while providing B vitamins, potassium, and a satisfying meaty texture from the mushroom's natural umami.
- Mayonnaise→Hummus
Hummus provides healthy monounsaturated fats and plant protein from chickpeas with about 60% fewer calories than mayo.
- White hamburger bun→Whole-grain ciabatta roll
Whole-grain flour retains the bran and germ, delivering more fiber, iron, and B vitamins per serving.
- Iceberg lettuce→Baby spinach
Spinach has roughly 7x more folate, 3x more vitamin K, and significantly more iron than iceberg lettuce.
- Ketchup (added sugar)→Balsamic vinegar marinade
Replaces 4 g of added sugar per serving with a naturally sweet, antioxidant-rich glaze that has zero added sugar.
