Zucchini vegetarian dish

Here is a vegetarian meal I enjoy. Another idea to deal with the over abundance of zucchini this time of year!

2 Tablespoons olive oil
1 cup rottini pasta, cooked according to package directions
1 medium zucchini, chopped
1 medium onion, chopped
1/2 green bell pepper, chopped
1 can tomatoe sauce
1 can kidney beans, drained and rinsed

In a skillet, cook the zucchini, onion, and bell pepper for 4 or 5 minutes. Add the tomatoe sauce, cover and let simmer for a few minutes. Add the kidney beans and pasta and heat through.
