Cucumber and Lettuce Vichyssoise is a refreshing and creamy chilled soup that is perfect for hot summer days. This classic French dish combines the crispness of cucumbers with the delicate flavor of lettuce, all blended together with creamy potatoes and rich vegetable broth. The result is a light and velvety soup that is both satisfying and cooling. Serve it as a starter or a light lunch, garnished with fresh herbs and a drizzle of olive oil.
