Prepare the shrimp by peeling and deveining if necessary, then patting them dry with a paper towel.
Heat a non-stick skillet over medium-high heat and lightly coat with a small amount of the olive oil.
Add the minced garlic and shrimp to the skillet, seasoning with sea salt and black pepper.
Sauté the shrimp for 2-3 minutes per side until they are pink, opaque, and slightly curled, then remove from heat to cool.
In a small jar or bowl, whisk together the remaining olive oil, lemon juice, lemon zest, chopped parsley, and chopped dill to create the vinaigrette.
In a large mixing bowl, combine the cooked quinoa, diced cucumber, halved cherry tomatoes, and finely diced red onion.
Add the cooled shrimp to the bowl and pour the lemon-herb vinaigrette over the top.
Toss all ingredients gently until well combined and coated in the dressing.
Serve immediately or refrigerate for 30 minutes to allow the flavors to meld.
