In an 8-quart stock pot heat 1 tablespoon of the olive oil on medium high heat. Once heated, place the sausage in the pan and brown nicely on both sides, about 3-4minutes per side. Remove sausage from pan with slotted spoon to a paper-towel lined plate and allow to drain. Discard all but 1 tablespoon of remaining grease.
Add remaining olive oil to pan, reheat to medium high and saute onion until just turning translucent, about 5-7 minutes. Add minced garlic and cook for another minute, being careful not to burn the garlic. Add carrots and saute for 3-4 minutes
Add broth, beans, parmesan rind, rosemary, kale, sausage, salt and pepper. Bring soup to just boiling, then lower temperature. Simmer (covered) for about 30-40minutes.
Serve with a drizzle of olive oil and some grated parmesan.
