Shaved Cucumber Greek Salad

Easy to make and absolutely stunning to look at, this fresh riff on a Greek salad offers beautiful flavor combinations. Mild Castelvetrano olives are meaty and buttery, green tomatoes are bright and acidic, green onions are pungent and savory, and feta cheese is creamy and salty. We love the subtlety of Champagne vinegar, but you can substitute white wine vinegar if you don't have it. Likewise with green peppercorns—they offer a different sort of peppery kick and stick with our color palette, but black peppercorns would also be delicious.
