My mother used to make mac n' cheese with tomatoes, so when I tried this recipe which I adapted from a canned tomato ad we loved it, even though it was quite different from Mom's. It is very different from our usual mac 'n cheese (which I already posted)and very good! Note 1: When I made this recipe I wanted to use up some evaporated milk that I had in the refrigerator - which was 1/2 can - this can easily be changed to using all cream or all evaporated milk to equal 1 1/2 cups total cream/evaporated milk. Note 2: cheese--I had about 1/2 pound of smoked and about 1/2 pound of regular Cheddar--although you should use some smoked Cheddar, I think his recipe is very adaptable to use whatever cheese is on hand and my amounts of cheese may be a little off by more or less than the amount listed in the ingredients as I did not measure the cheese but used what I had on hand. Note 3: I didn't use the hot dogs or little smokies but thought they would be great in this casserole.
