3tablespoonsfresh lime juice, about 2 small limes or one really juicy big one
1ripe avocado, pitted and cut into bite-sized chunks
For the quinoa:
Heat 2 tablespoons of olive oil in a medium sauce pan over medium heat. Add the diced onions and cook, stirring frequently, until soft and translucent, about 6 minutes. Add the dry quinoa to onions and continue cooking, stirring *constantly, for 3 minutes. Add vegetable broth and salt. Turn the heat up to high and bring to a boil. Cover pan tightly with lid, turn heat down to low and simmer for about 15 minutes, or until all of the liquid has been absorbed and the quinoa is cooked. Spoon the cooked quinoa to a heat safe mixing bowl and place in the refrigerator to cool.
For the corn:
Bring a large pot of water to a rolling boil. Add corn and cook corn for 4-5 minutes. Rinse with cold water until cool. Once cooled, cut corn kernels off cobs and place the kernels in a small bowl. Set aside.
When quinoa has cooled to at least room temperature, add the remaining tablespoon of olive oil, tomatoes, onions, corn, red bell pepper, scallions, jalapeno, cilantro, remaining and 2 tablespoons of lime juice. Taste and adjust seasoning if necessary.
Place avocado chunks in a small bowl, squeeze remaining lime juice over it, add a pinch of salt, and carefully (avocado is very delicate and mashes easily) stir to coat. Scatter avocado chunks over top of the salad right before serving.
