This isn't a gourmet meal or even remotely fancy, but it's simple and comforting and really quite good. I used ground turkey and since I only had a couple of tablespoons of sour cream, I used some plain yogurt in there as well. It sounds a little weird, but nice things happen in the oven. The key is to add enough salt. I tasted it before baking (you can do that, everything is already cooked!) and it was definitely not what I was expecting.....but when I added some more salt, it went from ho-hum to very tasty. The melted cheese on top was the final kicker. The kids and I ate most of this in two dinners while Grant was out of town...so if I'm going to make it while he's home and want leftovers, I'll up the proportions a bit.
Apparently this makes a great freezer meal....I haven't tried it yet, but I'm including the directions below.
