vegetable lasagna

i have found that non meat lasagna falls into two categories: 1. no vegetables and basically a baked spaghetti casserole, and 2. 600 ingredients. it should not have surprised me then that as i was half way through making this recipe i realized i had made it before. it's pretty simple and has a lot of spinach in it. however, this time i made a lot more modifications. i cut the cheese and noodles in half and subbed out one spinach box for zucchini and mushroom. this was pretty good but next time i will add in carrots, onions, and fresh tomatoes. also i'd rather start with a simple tomato base and add in my own spices, instead of relying on store bought. never as good.
i could not figure out what to eat with this lasagna. salad? there's already a pound of spinach in there. garlic bread? you want to eat pasta and bread? i don't know.
