Step 1
Start by warming the oil in a large pot over medium heat. Toss in the onion, celery, garlic, and thyme, and cook everything together until the celery softens, which should take about 7 to 10 minutes. Next, add the black beans, 4 cups of vegetable broth, and the cumin, giving it a good stir to bring all the flavors together. Then, stir in the white beans, the rest of the vegetable broth, and the sage. Let the soup come to a gentle boil, then reduce the heat and let it simmer for about 30 minutes so the flavors meld nicely.
