I like to slice zucchini and saute with a mass of sliced onions, julienned carrots, celery, peppers and any other veggies that I might have and would go with this. Add some chopped tomatoes along with a little salt, fresh ground pepper and any other herbs/seasonings that strike my fancy at the time. Eat it as is, as a side dish ... with fresh grated parmesan.
Another ... same saute mixture without the tomatoes, but with some canned diced tomatoes, makes a good veggie type stew.
How about zucchini instead of lasagna noodles? I always thought this was weird, til I tried it and well, I'm a convert!
