In a sauce pan add dry quinoa and water; bring to a boil then cover and reduce heat to simmer for 10-15 minutes. You will know quinoa is done when all the water is absorbed and the quinoa looks slightly transluscent.
While the quinoa is cooking; warm up a frying pan to medium heat and add the oil.
Mince the garlic and chop all other vegetables (and pear) into very small cubes (they need to be small so that they mix well with the quinoa and so you get a piece of everything with each bite).
Add garlic, and all chopped veggies (and pear) to frying pan, mixing occasionally. Cook until veggies are soft (~5-6 minutes).
Once qunoa is done add it to the frying pan and veggies.
Add the teriyaki (or soy) sauce (and butter if desired); season to taste.
Garnish with a sprig of parsley or chives and serve (can be served hot or cold; I prefer hot).
