Engine 2 Sweet Potato Lasagna is chock-full of vegetables (sweet potatoes, spinach, broccoli, carrots, mushrooms, onions and tomatoes), uses whole wheat lasagna noodles and tofu and has no added oil or salt. I substituted vegan parmesan for the ground cashews called for in the recipe, and added a teaspoon of Bragg's liquid amino acid (a salt substitute kind of like soy sauce) and a little cooking wine and water to deglaze the pan I used to make the vegetables.
P.S. I've started using My Fitness Pal's app for android to track what I eat and do for exercise each day. It's great for seeing how you are doing with nutrition and pretty easy to use and it's free. So far, what I've learned is on the Engine 2 challenge I eat whatever I want within challenge guidelines, but somehow still end up at or under the recommended calories to lose weight and hit most of my nutrients spot on (except iron, so more beans, spinach and raisins.)
