Cook the quinoa according to package instructions. Mine is heat 2 cups of chicken broth to a boil. Add 1 ¼ cup of quinoa. Reduce heat to low and simmer for 15 min with the lid on. Remove from heat and let sit for 5 min. Fluff with a fork. Set aside.
Meanwhile, heat a small amount of olive oil in a non-stick pan over medium heat. Add the diced shallot and cook, stirring for 2 minutes. Then add spinach. Cook spinach down until completely wilted and toss in the olive oil and shallot. Remove from pan.
In the same pan, heat another small amount of olive oil over medium heat. Butterfly the chicken breasts so they're thinner which will help them cook faster. Cook in the pan for about 5 minutes each side or until an inserted meat thermometer reads 165 degrees F. Sprinkle with some salt as they're cooking.
While the chicken cooks prep the veggies: dice the peppers and chop the green onions. Take mango chunks from the freezer and defrost in the microwave until room temperature.
Divide the cooked quinoa between 2 bowls. Add divided cooked spinach, diced red pepper and mango chunks. Top with the warm chicken breast.
Serve with peanut sauce, crushed peanuts, cilantro, green onions and lime wedges.
