Cook shrimp. Add enough grapeseed oil to coat the bottom of a large sauté pan. Heat the pan with the oil over high heat. Season both sides of the shrimp with salt and pepper, and once the pan is hot, add them to the pan. You should hear a sizzling sound -- if you don't, your pan's not hot enough. Wait until the pan is very hot and listen for the sizzle! Sauté the shrimp just until cooked through, about 1 to 1½ minutes per side. Set aside to cool.
Prepare pineapple. Drain the pineapple chunks over a medium-sized saucepan. Make sure to get all of the juice from the can -- it should measure exactly 1 cup. Set the pineapple chunks aside for later.
Cook quinoa. Add the coconut water and the soy sauce to the saucepan with the pineapple juice, along with the quinoa. Bring to a boil, cover, reduce the heat to low, and cook for 15 minutes.
Cool quinoa and mix everything together. Place the quinoa in a large serving or mixing bowl and let it cool completely. Add the lime zest and juice, onions, greens, pineapple chunks, raspberries, shrimp, and herbs. Mix it gently to combine, and season to taste with salt and pepper. (Here's how.)
