Cook in small pan and add your onion after you slice and dice them up , add your summer sausage and cooked ham after you dice them up ... you see everything is already cooked so all you are doing is adding favor to your canned bean. Bring the pan to a boil for about a min or three and dash a teaspoon of flour into the pan just to thicken it a little. This should be a 5 mins meal :-)
