Four Bean Casserole

Preheat oven to 180 C / Gas 4.

Place the bacon in a large, deep frying pan and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Drain the bacon slices on a kitchen towel-lined plate. Let cool and crumble.

Place the minced beef and onions into a large frying pan over medium heat and cook and stir until the meat is no longer pink, breaking the meat apart as it cooks, about 10 minutes. Drain any excess fat. Transfer the beef and onion mixture into a large casserole dish. Stir in the crumbled bacon, honey barbecue sauce, sausages and beans, kidney beans, butter beans, black beans, dark brown soft sugar, cider vinegar, liquid smoke, salt and pepper.

Cover and bake in the preheated oven until bubbling, about 1 hour.
