Begin by rinsing quinoa under cold water. In a saucepan, combine quinoa, 2 cups of water, and a pinch of salt. Bring to boil, reduce to simmer, cover, and cook for about 15 minutes until all water is absorbed.

While quinoa cooks, chop the vegetables: dice avocado, chop bell pepper, finely dice red onion, and halve cherry tomatoes.

Transfer cooked quinoa to a large bowl. Add black beans, halved cherry tomatoes, corn, diced avocado, chopped bell pepper, diced red onion, and mixed greens.

Drizzle olive oil and lime juice over the mixed ingredients. Season with salt and pepper, and toss gently to coat evenly.

Sprinkle chopped cilantro on top before serving or storing.
