Step 1: Prepare the Vegetables: Chop the onion and bell peppers into bite-sized pieces. Mince the garlic. This ensures even cooking and allows the flavors to meld effectively during the slow cooking process.
Step 2: Combine Ingredients in Crock Pot: In a 6-quart or larger crock pot, combine the sliced smoked sausage, chopped onion, bell peppers, minced garlic, crushed tomatoes, kidney beans, great northern beans, dried oregano, smoked paprika, and red pepper flakes (if using). Stir well to ensure all ingredients are evenly distributed.
Step 3: Season and Cook: Season the mixture with salt and pepper to taste. Be mindful of the salt content of the smoked sausage. Cover the crock pot and cook on low for 6-8 hours, or on high for 3-4 hours. Cooking times may vary depending on the specific crock pot used. The dish is ready when the vegetables are tender and the flavors have melded together.
Step 4: Serve: Once cooked, serve the smoked sausage and vegetable mixture over cooked rice or pasta, if desired. This adds a comforting base to the dish. Alternatively, serve it on its own as a hearty and flavorful stew.
Optional Tip: For a richer flavor, brown the sausage in a skillet before adding it to the crock pot. This step adds depth and complexity to the dish. Additionally, other types of beans, such as black beans or pinto beans, can be substituted based on personal preference.
