    I thought the sauce flavors worked really well. I made it a few hours ahead so the flavors had time to meld, so maybe that helped. What I didn't particularly care for is that this is a pretty labor-intensive recipe. Make the sauce, cook the zucchini, cook the pasta, assemble...... Not a recipe for me to make when time is short. However, I may very well make this again. Nice homey casserole!

    I used a jar of sauce to save time. Everyone loves this recipe and the leftovers taste just as wonderful the next day.

    I didn't use the sauce in the recipe and substituted my own canned homemade sauce. It took about a pint which I basically divided into thirds for the layers of sauce. We really liked this, and I will be making it again.

    This was not very good. I agree with the person who said it would have been good with different sauce. It's a good idea but didn't quite hit the mark for me.

    I find that the concept of this recipe is a great idea, but the sauce that you make out of the tomato paste/water/seasonings is very lacking in flavor and actually takes away from the lasagna. When I make this again, I'm going to use a jarred sauce or find a really good sauce recipe to make first.
