This was great! I've always liked roasted zucchini, but I'd never made it and this was super easy and delicious. Definitely spray the roasting pan because the veggies will stick! I laid down foil for easy clean up and I sprinkled the veggies with ground flaxseed for some added nutritional benefits.
