Cut bacon into pieces and fry in a pan. Once bacon is browned, pull it from the pan and set aside. Drain the water from the green beans and set water aside. Add green beans to hot pan with bacon grease, cook the green beans in the bacon grease for about 5 minutes, stirring. Add diced onion or a sprinkling of onion powder, now pour the reserved water from the cans into the pan and reduce heat. Keep warm on the stove until ready to serve.
