Quinoa Frittatas

Preheat oven to 400°F. Bring 1 cup water and quinoa to a boil in a small saucepan over high. Reduce heat to medium-low; simmer, covered, until quinoa is tender and water is absorbed, about 12 minutes. Remove from heat; let stand, covered, 3 minutes. Fluff with a fork. Let cool, uncovered, 5 minutes

Heat olive oil in a large skillet. Add kale; cook, tossing constantly, until well wilted, 1 to 2 minutes. Remove from heat; let cool about 5 minutes.

Whisk together eggs, cooked quinoa, wilted kale, cheese, and salt in a bowl. Line a 12-cup standard muffin pan with paper baking cups; coat with cooking spray. Spoon egg mixture evenly into prepared muffin cups. Dollop each muffin cup with 2 teaspoons pesto; gently swirl into egg mixture. Bake until frittatas are puffed and firm, about 18 minutes. Let cool in tray about 2 minutes.
