Heat olive oil in a large pot over medium-high heat. Add onion and celery; cook, stirring often, until the onion is translucent, about 5 minutes. Add garlic, stirring occasionally until aromatic, about 2 minutes.
Add the beans and broth to the pot. Bring to a boil over high heat. Reduce heat to medium-low and cook, stirring occasionally, until the vegetables are tender, about 20 minutes.
If you prefer your soup to be a combination of smooth and chunky, remove 2 cups of the soup and set aside. Using an immersion blender, process the remaining soup in the pot until smooth. Add the 2 cups of soup back into the pot and stir. (If you'd prefer your entire soup to be smooth, just skip this step and puree the entire pot of soup.)
Stir in the Dash™ Original Seasoning, Member's Mark™ Ground Black Pepper, and Member's Mark™ Sea Salt Grinder until combined.
