This is my variation on a recipe I found in a magazine. Garnish soup with fresh basil leaves and a drizzle of olive oil to serve.
Blend cucumbers, zucchini, onion, olive oil, basil leaves, and lemon juice together in a blender until smooth; add cream, salt, and pepper and pulse until smooth.
Refrigerate soup until chilled, at least 1 hour.
