Corn, Bean and Quinoa Salad

This weekend I did a simplified version of the Corn, Shrimp and Quinoa Salad. I didn't have any shrimp and I only had a little quinoa left, but I wanted a refreshing, nutritious salad. I loved how it turned out so I wanted to make note of it--

Corn, Bean and Quinoa Salad
1/2 cup uncooked quinoa
1 can black beans, drained and rinsed
1 can sweet corn, drained
1/2 green bell pepper, minced
1/4 c red onion, minced
1 scallion, thinly sliced
2 Tbsp fresh cilantro, minced
2 Tbsp extra virgin olive oil
1 Tbsp dijon mustard
juice of one lime (more if wanted)
1 tsp sugar
1/2 tsp salt
1/4 tsp black pepper

1. Cook quinoa according to directions. Let cool slightly.
2. Combine beans, corn, bell pepper, onion, scallion and cilantro in medium-sized salad bowl.
3. Whisk together oil, mustard, lime juice, sugar, salt and pepper and pour over corn mixture.
4. Add cooked quinoa and stir to combine. Refrigerate until serve.
