Heat olive oil in a 2-quart saucepan over medium heat. Season chicken with ⅛ teaspoon of salt and pepper, then cook 2–3 minutes per side until browned but not fully cooked.
Add sausage and cook 1 minute, flipping once.
Stir in onions and cook 1 minute, stirring occasionally. Add garlic and cook 30 seconds.
Stir in tomato paste and cook 30 seconds.
Add potatoes, corn, beans, diced tomatoes with juice, Worcestershire sauce, BBQ sauce, ⅛ teaspoon salt, and broth. Bring to a boil, then reduce to a simmer.
Simmer uncovered for 30 minutes.
Notes
Brown the Meat: Browning the chicken and sausage first adds rich flavor to the stew.
Use the Tomato Paste: It deepens the tomato base and balances the sweetness of the BBQ sauce.
Beans: Northern beans are creamy and mild, while lima beans are traditional. Use whichever you prefer.
BBQ Sauce Matters: A thick tomato-based sauce adds sweetness; Carolina-style brings a tangier, less sweet flavor.
Doubling the Recipe: Use a larger pot so the ingredients cook evenly.
