I do a Spinach Lasagna.
I have used sliced Mozzarella cheese, grated Mozzarella cheese, it doesn't matter at all which you pick.
I cook 2 packages of fresh frozen chopped Spinach as the directions state. Then I squish it out in a dish towel and roll it around to get all the water out. Set it aside to drain even more, like in a colander or strainer over the sink.
Then I start the noodles cooking in fresh boiling water. I add a tiny bit of olive oil to the water to make working with the noodles easier. I dump the noodles in a colander over the sink and then when they are slightly cooled I gently pick them up, one by one, and lay them out on oiled foil to make using them very easy. You can use this foil to cover the dish while cooking if you wipe it off a bit to remove excess debris.
I mix up the Spinach with some Ricotta Cheese, at least the small tub but sometimes O want the big tub and just don't use every last bit of it and add an egg and maybe a teaspoon of chopped or dried parsley. Set aside.
I love the Chunky Ragu Garlic and Onion spaghetti sauce so I don't make fresh sauce anymore.
To build the lasagna:
I grease the 13X9X2 pan with Olive Oil so clean up will go quicker.
I put 3 lasagna noodles on the bottom. I smear on about half the spinach mix onto the noodles then pour some sauce on the spinach mix, top with about 1/3 of my cheese, then repeat another layer, noodles, spinach mix, sauce, cheese...etc, this shallow of a pan will only do 2 layer successfully. If you have an actual lasagna pan it will be at least 1/2 inch deeper and you may be able to do 3 layers.
Finally I top with 3 more noodles and then heat it in the over covered with foil to keep the moisture in and fully cook the egg. After about 20-30 minutes I top with Mozzarella cheese and put it back in for just a few moments, maybe 3-5. just to melt the cheese. You should be able to put the foil back on to make travel easy. I spray the foil with a cooking spray, like regular Pam so the cheese won't stick when it's removed.
I have made this dish and traveled 3 hours away to a family reunion and just heated it back up when I got there. I wrapped the pan in a big towel and placed it on the back floorboards so it was flat.
