Best Vegetarian Lasagna; as Voted by 2/3 Kids?!

I have made and created many vegetarian lasagnas in my lifetime; this one is my best work. Even though it got 2/3 votes from my kids and their friend, the 4 year old was sick and grumpy so he doesn't count, he would have gobbled this up on a regular day!
I don't follow exact measurements so this recipe is a very close approximation to what I did. Feeling your way through the kitchen is a great way to tap into your creative side and reach heights of meditation that aren't possible in the classical meditation style.
Add more of the stuff you love and less of the stuff you don't!
Bolded are the ingredients required.
Enjoy.
2 - Orange or Red Bell Peppers
3 - Zucchini, sliced 1/2" thick
1 - large Eggplant, halved and sliced into 1/2" thick strips
8 - Vine Tomatoes
1/2 Onion
2 - cloves of garlic
Lightly brush above veggies with oil salt and pepper (Grapeseed oil is what I use for roasting).
Preheat oven to 450F, place the above veggies on a cooking sheet and roast for ~15 mins, until desired state of roast is reached!
-Puree Eggplant and peppers in a blender until saucy, set aside.
-Set aside zucchini, tomatoes, onion and garlic.
Meanwhile, boil water use appropriate number of lasagna noodles for your dish to make 3 layers (12 in my case). Cook for 2 mins less that indicated on the packaging.
6-8 - Crimini Mushrooms (or 2 portabella) rustically chopped
