An incredible salad. Cook so the spinach just gets warm and coated with the carmalized onion dressing! It smelled and tasted so good, I'm going to have to wait until next time to snap a picture of it. I usually serve this salad with some sort of white fish and other veggie as a main course. It may seem like a lot of butter, but it's what makes up the dressing and is necessary. I used "I can't believe it's not Butter" to cut the saturated fat in half that real butter would give and it came out great! The idea for this salad came out of a vegetables book in the grocery store and was a real winner!
