Modeled after an acclaimed New York eatery, this creative technique converts often-discarded external lettuce leaves into an luxurious herbaceous “mayonnaise”. It’s an smart way to reduce leftovers while making something flavorful and flexible.

Why Repurpose External Salad Leaves?

Those outer greens are the plant’s natural packaging, shielding the tender inner lettuce. While composting vegetable scraps is a fundamental sustainable practice, finding new uses for these parts is even more impactful. Turning surplus food into rich compost avoids landfill buildup, where they may release methane, a potent climate concern.

This is rather innovative when you think over it: produce decomposes and transforms into that ideal growing medium to feed more crops, thus closing the cycle and respecting nature’s process of growth.

Yet, with more than thirty percent extra food being produced than required, consuming valuable resources wisely is essential. Minimizing leftovers not only saves cash but also promotes the more sustainable way of living.

• 100g butter
• 50g external lettuce leaves from 2 romaine or butter lettuce, rinsed and dried
• 20 grams peeled salted pistachios – light-colored seeds like pine nuts help keep the vivid green, but any nuts will work

For the Salad

• Two romaine or butter lettuces, halved longwise
• Extra-virgin olive oil, as needed

Keep in an sealed jar in the refrigerator for as long as 3 days.
