Preheat the oven to 350F. In a large skillet, cook the sausage and onion over medium-high heat for 5 to 6 minutes until the sausage is browned and the onion softened. Add the pork and cook for 2 to 3 minutes longer until the meat is just heated through. Set aside. In a large bowl, combine the pork and beans, sauce, molasses, seasoning mix and liquid smoke, if using it. Stir well and transfer into a deep casserole. The dish should be large enough to hold the mixture so that it is no deeper than 4 inches and no shallower than 2 inches. Add the sausage/pork mixture. Stir well. Cook in the oven, covered, for 2-1/2 hours until hot and bubbling and the flavors are well- blended.

[Editor-If you're smoking some meat, put the beans in the smoker to cook. You'll get a delicious smoky flavor.]
