Speaking of veggie lasagna, Cottagebythesea makes a killer butternut squash lasagna! It's South Beach friendly - lowfat ricotta and mozz, with roasted and sliced butternut squash in place of pasta. DELICIOUS. I ate so much of it, I didn't have room for chocolate. And I didn't care!
She split the squash in half and roasted cut side down until they were browned on top, and then she peeled them with a knife and sliced the squash in to 1/2 inch or so slices. It doesn't matter if they wind up in uneven pieces - sheets of squash would be nearly impossible to slice! Just get the thickness approximate for each layer, and use in place of the pasta in your favorite lasagna recipe. Yummers!
