Repurposing Outer Salad Greens into Creamy Mayonnaise – An Zero-Waste Recipe

Drawing from a popular New York restaurant, this creative technique converts typically wasted outer lettuce greens into a smooth green emulsion. This is a brilliant approach to minimize food waste while producing a condiment delicious and adaptable.

The Reason Use Outer Salad Leaves?

These external greens are nature’s protective packaging, guarding the tender inside leaves.
