In a medium bowl, toss the shrimp with olive oil, garlic powder, paprika, salt, and pepper.
Heat a skillet over medium-high heat. Add the shrimp and cook for about 2-3 minutes on each side, or until they turn pink and opaque. Remove from heat and set aside.
In a large bowl, combine the mixed salad greens, cherry tomatoes, cucumber, red bell pepper, red onion, and cilantro.
In a small bowl, whisk together the lime juice, fish sauce, honey, sriracha, and ginger to make the dressing.
Pour the dressing over the salad and toss to combine.
Top the salad with the cooked shrimp and sprinkle with chopped peanuts if using.
Serve immediately or chill in the refrigerator for 15-30 minutes for a refreshing taste.
