White bean and chard soup

Perhaps this is not the most summery dish, but an excellent way to use up a head of beautiful red chard, nonetheless. (Plus a lot of homemade broth.)

1 bag white beans, pre-soaked and drained
1 onion, chopped
3 carrots, chopped
3 stalks of celery, chopped
olive oil
1 head of chard (or other leafy green), destemmed and chopped
Seasonings: salt, pepper, red chili flakes, cumin, parsley, Italian seasoning
broth

Saute the onion, carrots and celery in olive oil until soft. Add the beans and enough broth to float it all; simmer covered on low until the beans are tender. Add chard and seasonings to taste. Simmer another five minutes and serve, possibly with parmesan sprinkled on top.
