Assorted peppers with onions, kidney beans and swiss chard

This is a yummy veggie dish will make a great side with anything. All of the vegetables came from my garden, except for the kidney beans and the zucchini. I didn't have enough room in my garden to grow zucchini this year. They're easy and very inexpensive to find at roadside stands.

1 cup of kidney beans
Sea salt and pepper to taste
In a large saucepan saute all veggies in olive oil over medium heat, uncovered until tender.
once finished, add the kidney beans and season with salt and pepper.
