I have made this about twice. I am not a big fan of the boxed cornbread mix, but when I have used it, (very seldom) I add a couple of teaspoons of sugar and one of flour. I prefer my cornbread northern style. It takes the grittiness out of the mixture and adds a slight bit of sweetness. My kids are all middle age now, but I do remember making it for them when they were kids. Haven't thought of this dish in eons. I do remember it being a BIG hit with my husband on a Sunday morning. What man doesn't like hash? For him, I served a poached egg on top of his serving.
Illegitimi non carborundum!
I don't want my last words to be, "I wish I had spent more time doing housework"
