If you have any tomato sauce or a can of crushed tomatoes, you can gently reheat the lasagna, with some of this sauce spread over it.
Use a covered dish in the oven to get some steam going.
Even water, added over the top (a small amount), seal the whole thing with foil, and then reheat at a low temp -- will make a difference.
Spread some more sauce over it. Put a pan of water in the oven on the rack underneath while reheating to give some moisture.
Ain't no thing.
