If using raw shrimp, bring a pot of salted water to a boil and cook for 2-3 minutes until shrimp are pink and opaque. Drain and rinse under cold water.
If using pre-cooked shrimp, simply thaw (if frozen) and pat dry with a paper towel.
Thinly slice the cucumbers and red onions.
Halve the cherry tomatoes and chop the parsley or dill.
In a small bowl, whisk together olive oil, lemon juice, Dijon mustard, honey, minced garlic, salt, and black pepper until well combined.
In a large mixing bowl, combine shrimp, cucumbers, red onions, cherry tomatoes, and herbs.
Pour the lemon-herb dressing over the salad and toss gently to coat everything evenly.
Serve immediately or refrigerate for 15-30 minutes to let the flavors meld together.
Enjoy as is, over a bed of greens, or with crusty bread on the side.
