I suppose this is much better than the processed stuff.

Ingredients
3 (8 ounce) cans tomato soup
1 (8 ounce) can water
1 (8 ounce) can milk
1 lb small shell pasta, rings alphabets
6 ounces shredded Velveeta cheese
salt
Directions
1Cook and drain pasta according to package. Mix all ingredients together, heat through until cheese is melted.

I forgot to add, I'm sure you can make it even healthier, just trying out different ingredients too. I personally am NOT a fan of velveeta so I'd try other kinds first.
