Cook the quinoa in boiling water until they burst and become little spirals, about 15 minutes. Drain if needed and return to pot.
Heat the oil in a medium skillet over medium-high. Add the onion and cayenne chili, and saute until softened and starting to brown, 6 minutes.
Add onion mixture to the pot with the quinoa, along with the salmon and spinach. Toss to combine. Give a good pinch of salt and pepper to the mix. Spritz with lemon and get all healthy!
