Black Bean, Corn, Quinoa Salad

2 cups cooked quinoa
1/2 cup diced red onion
1 cup corn
1 (15 ounce) can black beans, drained
1/4 cup chopped cilantro
1 large tomato, diced (I remove the seeds and juicy stuff)
1/2 cup fresh lime juice, or to taste
2 tablespoons red wine vinegar
2 tablespoons olive oil
1 tsp ground cumin
1/4 tsp garlic powder
1/4 tsp cayenne pepper
3/4 tsp coarse salt (or 1/2 tsp table salt)
black pepper to taste

In a large salad bowl, mix together red onion, corn, black beans, cilantro, tomato; lightly stir in the quinoa. In small bowl, whisk together lime juice, red wine vinegar, olive oil, and spices. Season with salt, pepper, and additional lime juice to taste, if desired. Chill the salad at least 30 minutes before serving; serve cold.

This is my own version of a salad I found online. I've made significant enough changes that I can call it my own. The cayenne adds a nice kick!
