A vegetarian lasagna? In my house? This was a bold move. There is ground rule in my house, they will try any meat and they will most likely like it. No, they are not against vegetarian dishes – but whenever I have brought up a vegetarian lasagna in the past I always got the same response, “Lasagna should have meat in it. Until now. Sorry folks. When I saw this recipe at Pinterest, I knew I had to make it. I LOVE cheese, pesto, spinach and mushrooms – so of course I should love it!
