Pat the shrimp dry with a kitchen towel and season with garlic powder, paprika, salt, and pepper.
Heat olive oil in a medium skillet over medium heat. Cook the shrimp for 2-3 minutes per side, until pink and opaque. Remove from heat and set aside.
In a saucepan, bring 2 cups of water to a boil. Add quinoa, reduce the heat, cover, and simmer for 12-15 minutes until the water is absorbed. Fluff with a fork and let it cool. Set aside.
In a small bowl, whisk together olive oil, lemon juice, Dijon mustard, garlic, honey, salt, and pepper. Set aside.
In a large bowl, combine the cooked quinoa, cucumber, red onion, bell pepper, parsley, and feta cheese. Mix well.
Add the cooked shrimp and drizzle the prepared dressing over the salad. Toss to combine.
Enjoy immediately or chill in the fridge for 15-30 minutes to let the salad flavors blend!
