This was awesome!!! I suck at meatloaves and I didn't press the meat together enough after the cheese/sour cream layer, so much of the goodness cooked out and it didn't slice nicely, but the flavour was delicious. I only had one envelope of taco seasoning, so that's all I used, but it was wonderful anyway perfect. Will definitely make this again -- and this time I'll make sure it seals around the filling!
Great and easy to make. I used ground turkey instead of beef.
