This is the worst lasagna I've every had! Why Change?

WHY!!! Why change the PC Vegetable Lasagna Recipe as a number of customers, including myself and extremely dissatisfied and not understanding why on earth anyone in their right mind would alter an amazing recipe. I normally kept one in my freezer as a staple. This is very disappointing. I won't purchase again unless the change the recipe back to the one without mushrooms and more real vegetables!!! I've been eating this lasagna since 2004 and always good until this point (stopped buying in 2018!!!!
