Toss the shrimp with olive oil, red pepper flakes, cumin, and salt.
Heat a skillet and cook the shrimp for 2-3 minutes on each side until pink and cooked through. Set aside to cool.
In a large salad bowl, layer lettuce or arugula as the base.
Top with mango, cucumber, red onion, avocado slices, and roasted cashews.
Whisk together olive oil, lime juice, honey, ginger, salt, and black pepper for the dressing.
Add the shrimp to the salad, drizzle with the dressing, and serve immediately.
