I made this the other day and my husband just loved it and says it is better than “real” lasagna. I used a package of my frozen homemade garden tomato sauce. I also added a bit of red wine to the sauce. I still have fresh herbs, even though the weather is getting really cold here.

We bought a spaghetti squash yesterday and a jar of pesto - my husband had seen a recipe where you toss the squash with pesto, and that sounded very good.
He’s big on the ‘low-carb’ diet, and your recipe sounds like one he’d like.
