I made this for dinner for the first time and decided to alter it just a bit. I used left over ham, peas and carrot mix, and I added some Velveeta and an onion. I also swapped sour cream for the milk to make it a bit more creamier. It was very good and made more than what I expected- I had to use a 9x13 pan. I will definately make this again for my kids!!!!
