I've had this ultra-easy recipe for many years. No cooking needed, just a food processor or blender. It doesn't get much simpler. For variety you could add some dill or other fresh herbs, a handdful of raw or cooked spinach or leftover peas, even a ripe avocado. No cream? Use whole milk, buttermilk or Greek yogurt! I recommend unwaxed cucumbers. Lime juice can be substituted for lemon if you add some green chiles to the mix.
