That Baked Bean Recipe I Promised Lori

Lori, here's that recipe I promised you a week ago. Sorry for the delay :-
I can cook at last count three things: those perennial greats lasagne and chili, and the bean recipe below. [Typical male.]

1 20-oz can pork and beans in tomato sauce
1 20-oz can five-bean mix
1 20-oz can red kidney beans
1/2 pound bacon
2 large white onions
1/2 cup vinegar
1 cup brown sugar

Drain the beans and dump them into a baking dish.
Chop up the bacon and onions and fry them until the bacon is crisp.
Mix the vinegar, sugar and fried bacon and onions and cook them in a frying pan for 20 minutes: then pour everything over the beans and bake it all for 1 hour at 300.
Better reheated the next day after being refrigerated overnight.

Gordon Ramsay, look out. BTW, unlike Gordon (see this page), I don't scream obscenities while cooking.
