6 slices bacon
Warm a large bowl by filling it with very hot water. Fry bacon, remove from pan, and set aside to crispen. Pour water from bowl and dry it. Put cut lettuce into the bowl. Add vinegar, salt, sugar, pepper to hot bacon grease and pour over lettuce immediately. Cover bowl and let lettuce wilt for 5 minutes. Uncover and sprinkle with crumbled bacon, green onion, and grated egg, if using. Serve at once.
COOK'S NOTE: Some folks like to add the green onion in with the lettuce. Either way is fine.
