I had the lasagna. It turns out I was mistaken about the cheese being one layer on top. It's pretty pervasive. And there are two different kinds.
See, I work M-F, 9-5 and my husband cares for our son and does the cooking. On weekends, we swap. I came home so hungry and I thought, "I hope he didn't make lasagna." And he had. He's had a really bad cold lately and had very little energy today, hence the "throw something in the oven" type option.
I didn't enjoy the lasagna. I used to love it, but it tasted too salty and heavy for me. And almost immediately I had a headache. I don't know if the lasagna is to blame or if it's coincidence (or maybe even psychosomatic). But I'm thinking I'll skip the lasagna next time it comes up. Maybe over the weekend I'll do a bunch of cooking so I have a backup plan.
