Preheat oven to 400 degrees, line a baking sheet with parchment paper. Place the salmon fillets on to the sheet. Brush the salmon with 1 tablespoon of the oil (reserve the second tablespoon for later) and season with salt and pepper. Bake for 15 minutes until firm and flaky.
Meanwhile, heat the remaining oil in a skillet. Once hot, add the garlic, kale, and carrot. Cook, stirring often, until the kale is wilted and soft. Add the quinoa and cashews. Cook, stirring, just until hot.
Spoon the kale and quinoa mixture into a serving bowl. Remove the salmon from the oven and place on top of the kale. Serve and enjoy.
Optional Yogurt Sauce
In a small bowl, combine all ingredients and mix well. Let sit for about 10 minutes. Drizzle over cooked salmon, and enjoy!
