That was a good thought. Found this on a 'food reference' site:
The origin of the expression "bringing home the bacon" is uncertain. It might come from the English custom, which originated in the 12th century, of giving a young couple bacon if they were still happy after a year of marriage. Maybe it comes from the 'greased pig' competition at fairs, the winner bringing home the bacon (the pig). Or maybe bacon is meant to represent all food, since it is very ancient, having been a favorite of the early Romans and Greeks.
