Quinoa with Walnuts and Shallots

From Bon Appetit.
Ingredients:
3 Tbsp. walnuts
1 c. red quinoa
1 Tbsp. olive oil
2 shallots, sliced
1/2 tsp. kosher salt, plus more to taste

Preheat oven to 350°. Toast walnuts on a small rimmed baking sheet, stirring occasionally, until fragrant and slightly darkened in color, 6–8 minutes. Let cool; coarsely chop.
Meanwhile, thoroughly rinse quinoa; drain.
Heat oil in a medium saucepan over medium heat. Add shallots and 1/2 tsp. salt; stir to coat.
Cook, stirring occasionally, until shallots have softened, about 5 minutes. Add quinoa and stir to coat. Pour in 1 1/2 cups water, increase the heat, and bring to a boil. Reduce heat to low and cover. Cook until quinoa is tender and the germ has unfurled, 15–18 minutes. Season with salt. Just before serving, toss in toasted walnuts. Reserve ½ cup quinoa for Quinoa and Roasted Vegetable Salad.
Makes 4 servings.
