Choose your substitute based on dish type: for raw crunch use romaine or green leaf; for soft wraps use butter lettuce; for cooking choose napa cabbage.
Wash and drain the chosen greens thoroughly to ensure crispness and remove excess moisture.
Measure substitutes by volume according to recommended ratios (mostly 1:1) and prepare by chopping or shredding as needed.
If using napa cabbage in cooked dishes, slice thinner than iceberg to aid texture and flavor integration.
Adjust seasoning and check texture before serving, especially for softer leaves like butter lettuce that wilt quickly.
