Wash the fresh cucumbers and broccoli under cool running water. Chop the cucumbers into bite-sized pieces and cut the broccoli into small, uniform florets.

Scoop the ripe avocados into a medium mixing bowl. Mash the avocados until smooth, leaving a few small chunks for added texture.

Combine the sour cream with freshly squeezed lemon juice in a separate bowl. Whisk until well blended and creamy.

Add the chopped cucumbers and broccoli to the mashed avocado. Pour the prepared dressing over the top and gently fold all ingredients together.

Sprinkle in chopped dill or parsley along with salt and pepper. Toss lightly to distribute the herbs throughout the salad.
