Bring a pot of water to a boil. Add the shrimp and cook for 3-5 minutes until pink and opaque. Drain and place in a bowl of ice water to cool. When cooled, pat dry and cut into bite-sized pieces.
Mash the avocado and season with salt, lemon juice, and garlic powder if using.
Toss the shrimp, avocado mixture, diced cucumber, dill, and chives together. Adjust seasoning to taste. Serve chilled.
Notes
This salad is excellent as a light lunch or a refreshing dinner option. Try it with crusty bread or over greens for added texture.
