In a large pot over medium-high to high heat [note #2], saute onion, garlic, carrots & celery until onions are fully translucent and there is some browning on the bottom of the pan, about 10-14 minutes
Add tomatoes to deglaze the pan and cook them down until they've begun to caramelize and brown, another 10-20 minutes [note #3]
Add beans, potatoes and water and bring to a boil. Reduce to a simmer and cooked uncovered for 10 minutes, until potatoes are soft
Stir in the chopped kale, cover, and cook for an additional 2 minutes
Serve by itself, with cayenne, salt & pepper, frozen corn, over rice, with toast, or cool and store for the week
Enjoy!
