I just made the ground beef one tonight. It was really good, although I did change it a bit. I added taco seasoning to the beef, and I mixed refried beans and some queso dip and put that on top of the beef. I also used red pepper instead of green onions, as I didn't have any onions. Both my husband and my son had second helpings. Which for my husband, that's huge, because he's not a big casserole fan.
