For an extra burst of flavor, consider adding a squeeze of fresh lemon juice to the dressing. If you prefer a tangier salad, you can substitute plain Greek yogurt for some of the sour cream. Make sure the shrimp is fully cooked and chilled before using it in the salad. Overcooked or warm shrimp can affect the overall taste and texture. This salad is best enjoyed fresh. While it can be stored in the refrigerator for up to 24 hours, the texture may change slightly. Serve with crackers, lettuce cups, or as a filling for sandwiches or wraps.
