Pepper Parmesan Beans

I make a green bean side dish with feta cheese which has become a Christmas fan favorite over the years.  This would be a little different spin.
1 sweet red pepper, diced1 small green pepper, diced
1/4 C. chopped onion-->I have family members that don't like onions so I may just use onion powder here
1 garlic clove, minced
1/4 C. olive oil
1 1/2 pounds fresh green beans cut into 2 inch pieces
1 tbsp. minced fresh basil or 1 tsp dried basil
1 tsp salt
1/3 to 1/2 C. shredded Parmesan cheese

In a large skillet, saute the peppers, onion, and garlic in oil until the vegetables are tender, about 3 minutes.  Add the beans, basil and salt; toss to coat.  Cover and cook over medium low heat for 7-8 minutes or until the beans are crisp tender.  Stir in the cheese; serve immediately.
