It can be made without or with less margarine and with skim milk.

Cheesy Pasta Flavor prepared low-fat (210 cals per serving/45 from fat/1.5 grams
of saturated fat):

That's more or less what I was trying to do. One more set of ideas based on Tuna
Helper.

That same version (Cheesy Pasta) unprepared has 180 cals per serving, with 32
cals from fat (1 gram of sat fat). You could make it with a combination of skim
milk and a couple tablespoons of fat-free ricotta or fat-free cottage cheese
(whiz it all up with the milk in the blender). If you think it really needs some
butter flavor, add some Molly McButter or Butter Buds or a shot of Smart Squeeze
or the fat-free Parkay mist/spray. Those won't add any calories (the Smart
Squeeze is 5 cals per tablespoon, iirc). Just some ideas.

You could do much the same from scratch with some fat-free noodles or pasta,
tuna, the fat-free ricotta or cottage cheese, and other spices and veggies as
you like. It would knock off a few more calories per serving and reduce the fat.

Let me know if you try doing it either from scratch or with Betty Crocker's
stuff. I'm curious how it turns out stuffed in tomatoes.
