Method
Heat grapeseed oil in a heavy-bottomed skillet over medium-high heat. When hot, but not smoking, put in onions and both red and yellow peppers. Cook, stirring, over medium heat until softened, about 5 minutes. Add garlic, and cook for about 2 more minutes.
Stir in quinoa, vegetable stock, and tomato puree. Bring to a boil. When boiling, lower heat immediately and cook, covered, at a rolling simmer for 15 - 20 minutes, or until quinoa grains are soft.
Stir in the diced tomatoes and season with oregano, salt and freshly milled pepper to taste. Cook just to heat tomatoes.
