One of the commenters used her own fresh made bread and then used spaghetti squash. Just for the very reason of carbs.
I think the first time I'm going to make it I'll use Mom's pizza dough recipe with less of the spices, just cause I know the outside will be yummy then.
Yea, I make my own bread too, so when I do make it, it'll be with homemade bread, and at least once with sourdough (that's hands down the favorite bread around here).
Alas, no one in this house likes spaghetti squash (blech!) so I won't be using that. One thing I may wind up doing is chicken breast slices with assorted vegetables (califlower, broccoli, carrot, bell pepper, see if I can sneak some zucchini past the boyfriend) and a light teriyaki or bbq sauce.
Ooh, just thought of another interesting thing to do with this. Instead of spaghetti, build a small lasagne (one or two noodles wide) and wrap the bread around it.
