Can frozen spinach be substituted for fresh?

Hi there! Yes, it can be. :) Enjoy!

I have hard time getting my diabetic husband to eat the veggies he needs, but he likes eggs and he likes cheese, so I tried this recipe. It turned out great and it made a pretty presentation with the green and yellow color contrast, and lo and behold, he not only liked this casserole, he asked for seconds and called it a keeper. Loved this result and would recommend it to any and all!

We're glad that you and your family enjoyed this recipe! )
