How to Make It
In a medium pot over high heat, bring the quinoa, water and 1/2 teaspoon kosher salt to a rolling boil, stirring occasionally. Reduce the heat to low, and simmer until the quinoa has fully absorbed the water, about 15 minutes. Remove from the heat.
In a serving bowl, toss the quinoa with the olive oil, feta, scallions, mint, and salt and pepper to taste. Serve warm or chilled.
