I have a challenge for you foodies out there...

actually, summer or spagitti squash and cheese would work too.  I would drop the bread.

How about black bean and salsa instead of mac and cheese and cheese?

Lin - great idea!  I love salsa - but may think about the low fat refried beans and salsa.  that was a staple for me post surgery

I love the ideas for adding beans and subbing in eggplant, cauliflower, or spaghetti squash for the macaroni. Quinoa could work, too, although it would be higher in carbs than veggies. As for the cheese, maybe go with a higher protein, lower fat option like Unjury Protein'd cheese sauce?

Or maybe use the quinoa to sub for the bread layer?

My daughter uses quinoa a lot in her cooking - may be an option.  

I did not know Unjury had a cheese sauce... may need to look into that

What about using spaghetti squash in place of the mac noodles and omitting the bread?

I would ditch the bread and use cauliflower and cheese in place of mac and cheese.
