Thread the shrimp onto wooden skewers that have been soaked in water for at least 30 minutes and set aside.
Bring the water to a boil and add in the quinoa. Cook until all the water has been absorbed, then turn off the heat and place a lid on the pan.
Mix the juice from the oranges with the balsamic vinegar, olive oil, and a pinch of salt and pepper.
Brush a skillet with olive oil and cook the shrimp until opaque, about 3 minutes per side.
Toss the spinach and arugula with the cooked quinoa and divide between two bowls. Drizzle over the dressing.
Sprinkle with cherry tomatoes and lay the shrimp skewers on top
