Cook 1 cup of quinoa according to package directions. Fluff with a fork and set aside.

While the quinoa is cooking, prepare the vegetables. Dice 1 red bell pepper, 1 cucumber, and ½ cup of cherry tomatoes.

In a large bowl, combine the cooked quinoa, diced vegetables, ½ cup of black beans (rinsed and drained), and ¼ cup of crumbled feta cheese.

Drizzle with 2 tablespoons of olive oil and 1 tablespoon of lemon juice. Season with salt and pepper to taste.

Garnish with fresh parsley or cilantro, if desired. Serve immediately or chill for later.
