Rinse the quinoa. Place quinoa in a medium pot and add 2 1/2 cups water. Boil for 20 minutes until the quinoa has popped or water has evaporated. Leave it on the side after cooking.
Heat the olive oil in a skillet over medium heat, stir in the pine nuts, and cook until lightly toasted, about 2 minutes. Stir in the red onions and garlic, and cook until the garlic and red onions softens, about 2 minutes.
Stir in the quinoa and swiss chard; cook and stir until the quinoa is hot, and the swiss chard has wilted. Stir in the lemon juice, and all but a pinch of the cheese. Stir until the cheese has melted. Serve sprinkled with the remaining cheese.
