Bring chicken broth to a boil in a sauce pan and stir in the couscous. Cover the pot and remove from heat. Let stand for 5 minutes.
In a large bowl, whisk together the olive oil, lime juice, vinegar and cumin. Add green onions, red pepper, cilantro, corn and beans and toss to coat.
Fluff the couscous with a fork, breaking up any chunks. Add to the bowl and mix well. Season with salt and pepper to taste. Refrigerate until ready to serve.
Notes
You don't need to cook the couscous in chicken broth. You can use the same amount if water, just make sure to add a teaspoon of salt and a couple teaspoons of butter or olive oil.Source: Allrecipes.com
