Gather the ingredients.

Place 6 eggs in a medium saucepan with enough cold water to cover. Bring water to a boil, and immediately remove from heat. Cover, and let eggs stand in hot water for 10 to 12 minutes. Remove from hot water, cool, peel, and chop.

Place bacon in a large, deep skillet. Cook over medium high heat until evenly brown. Drain, crumble, and set aside, reserving approximately 1/2 cup of drippings in the skillet.

Toss spinach and green onions together in a large bowl.

Heat the reserved drippings over low heat. Whisk 2 remaining eggs, sugar, white vinegar, and red wine vinegar together in a small bowl; add to warm drippings and whisk until thickened, about 1 minute.
