These were awesome! I loved the flavors of the onion and spinach together. I left the frozen spinach box in the fridge overnight and it thawed out just fine. I think this could be made even more healthy with some ground turkey. I will make this again. Made and Reviewed for Please Review my Recipe Tag - Thanks :)
My husband really liked these. I, however, found out I don't like onion soup mix in my burgers. Sorry, just couldn't find the love! We both thought the spinach and cheese in the burgers was wonderful. Added some sauteed mushrooms and swiss cheese on top. If you like onion soup burgers, I think you will really like these. I think I will fiddle around on my own and see if I can come up with some spices I will like better to go with the spinach. Husband rated them as 3.5 but I always round up. Thanks for the posting!
