I learned about butternut squash mac & cheese on this forum a couple of years ago. I found
this recipe from Martha Stewart and tweaked it to make it Beach-friendly: ww or brown rice elbows, ww bread crumbs, more ricotta/add cottage cheese to add protein... plus (as I just posted in the Fabulous Foods section), I microwave the whole squash first - poked MANY times deeply, then on high 10-15 minutes until soft - instead of peeling and cubing a hard raw squash. I get many requests to make this, it is quite delicious and comfort food-y.
I posted my tweaks here, just ignore the spaghetti squash substitution for pasta, it was something I was experimenting with (comes out almost like a dessert that way!).
mmmm, now I want to make this! The lasagna and soup ideas sound good too. I have to go pick my squashes now
