Heat 1 tablespoon oil in a large pot over medium-high heat. Add sausage and brown on both sides, about 3-4 minutes. Drain all but 1 tablespoon of oil.
Add onion, red bell pepper, and garlic and saute until vegetables are softened, about 5-7 minutes. Add canned diced tomatoes, smoked paprika, bay leaf, and thyme. Bring to a simmer, reduce heat to low, and cook for 20 minutes, stirring occasionally.
Add chickpeas and chicken broth and simmer for another 15 minutes. Add spinach, and cook until spinach is wilted, about 3 minutes. Season with salt and pepper and discard bay leaves and thyme. Serve.
Notes
Use cured Portuguese sausage, also known as linguica sausage.
