Just made it yesterday. Wife won't touch it.
Fry bacon
sauté onion in bacon grease, I usually put onions in on the last turn of the bacon.
Put nice fat cheese burger on the grill now.
flour/salt/pepper on liver
fry liver in bacon grease.
Feed liver and bacon grease you ruined to the dog. ( only do this if your dog lives outside and you have a love hate relationship)
Go back inside and enjoy your bacon cheeseburger with delicious grilled onions.
Medium low heat (same as normally cook bacon)
I like white gravy some prefer brown
mashed or boiled taters with gravy helps it go down
