Add quinoa and 1 tbs. of olive oil to a pot on medium-high. Once the water is boiling, cover and reduce to low heat. This should take about 15 minutes, but check regularly until the water is absorbed. Fluff with a fork when finished.
Make your cilantro jalapeño dressing by adding the olive oil, 2 tbs. of chopped cilantro, jalapeño, lime juice, and a pinch of salt and pepper into a blender or magic bullet. Blend until evenly mixed and set aside.
In a medium to large bowl, add the cooked quinoa, corn, onion, avocado, blueberries (optional), and 1 tbs. of chopped cilantro. Sprinkle with feta and top with the cilantro jalapeño dressing. If you're planning on eating throughout the week, add the cilantro jalapeño dressing separately to prevent the salad from getting soggy.
Share with others or have it as a dinner, lunch, and snack throughout the week. Enjoy!
