I started this recipe and realized I didn't have all of the ingredients. First I doubled the ham b/c I used a spiral cut which was thin. I still feel I could have used more. I didn't have cheddar so I added 8oz or so of Velveeta into the milk mixture. I had a bit more noodles and I used crushed veggie Ritz crackers in place of pretzels. I thought it was excellent and is a very versatile recipe. It will be my go to casserole for leftover ham, turkey, chicken and I may also try tuna.
