Begin by preparing your ingredients for the Cucumber Avocado Feta Salad. Peel and pit the avocado, then cut it into bite-sized cubes, setting it aside to prevent browning. Next, take the cucumber and partially peel it, slicing it into similar-sized chunks. Crumble or cube the feta cheese into a separate bowl and finely chop the fresh dill for vibrant flavor.

In a large mixing bowl, combine the chopped cucumber, avocado, feta cheese, and fresh dill. Gently fold these ingredients together with a spatula or wooden spoon, ensuring they are evenly distributed without mashing the avocado or feta.

Now it's time to season your salad. Add a generous sprinkle of salt and freshly cracked black pepper. Drizzle your mixture with olive oil, then squeeze half of the freshly juiced lemon over the top along with some lemon zest. Gently toss everything together, careful not to break up the avocado further.

To serve your refreshing Cucumber Avocado Feta Salad, arrange it on a bed of fresh lettuce leaves for added color and crunch. Garnish with extra lemon juice, salt, pepper, dill, and a touch more lemon zest for a fragrant finish. Serve immediately.
