How to Make It
Cook oil and garlic in a large saucepan over medium until garlic begins to brown, 4 to 5 minutes. Remove and discard garlic; reserve 3 tablespoons of the garlic oil.
Increase heat to medium-high. Add sausage to pan; cook, stirring often, until browned and crumbled, about 6 minutes. Remove sausage from pan; drain on paper towels. Add onion, celery, and carrots to pan; cook, stirring occasionally, until slightly tender, about 4 minutes. Stir in broth, tomatoes, chickpeas, and pepper; stir in sausage. Bring to a simmer; reduce heat to medium-low, and cook 20 minutes. Stir in kale; cook until wilted, about 5 minutes. Drizzle each serving with 1/2 tablespoon reserved garlic oil.
