Melt butter in a saucepan over medium heat. Add the quinoa, garlic and onion, and cook, stirring occasionally until the quinoa is lightly browned.This takes about 5 minutes. Stir in broth and bring to a boil. Reduce to a simmer, cover and cook for 15 minutes or until quinoa is tender.
In a bowl toss the quinoa mixture together with the parsley, thyme, and salt. Sprinkle with lemon juice and serve.
