Zucchini Lasagna

I have been trying new ways to sneak in more vegetables in my meals.  I saw a version of this online.  It was so good!

Step 1:
Wash and slice zucchini into 1/2 inch coins.  Place them in a bowl and toss with a small amount of olive oil.  Add Italian Panko bread crumbs and toss again, until zucchini is mostly covered.  Spread them out of a baking tray and roast at 375 for roughly 25 min.

Step 2:
Brown two hamburger with onion (if desired). Saute fresh sliced mushrooms separately (if desired).

Step 3:
Layer zucchini, hamburger, mushrooms, and spaghetti sauce.  Top with shredded mozarella cheese and more Italian Panko bread crumbs.

Step 4:
Bake at 350 degrees until heated through.
