    We loved it. Hubby said it was a definite keeper and was even better the next day. Only changes I made based on some other readers was to make sure the water was squeezed out of the zukes, and I added a can of mushrooms, Italian herbs, and extra mozzarella (because I had it). Can't wait to make it again. Next time am going to add Italian sausage to it. Great recipe.

    Made this again with turkey sausage instead of the hamburger. Much tastier, and hubby loved it. So need to up the rating to a 5 instead of a 4. Would definitely have again and again

    Excellent! Was looking for another low carb dish when I found this. I sauteed some chopped mushrooms and added them to the sauce, omitted the pepper cause we don't like it. I used marinara sauce that was low in sugar in place of the tomato sauce. This is very tasty! My hubby suggested next time to use Italian sausage instead of ground beef but I thought it was perfect.

    My husband said this is a keeper. I added some red pepper flakes to the zucchini mixture, Used Prego pizza sauce & added garlic & Italian seasoning to the meat. He is on a low carb diet.

    So versatile! I liked the posted review of the Mexican version as well. For that, I would switch the tomato sauce for enchilada sauce, or thick salsa drained slightly. Cheeses would be all cheddar or chedder/ & cheddar Jack for some spicy kick . Seasoning would be cumin or low sodium taco seasoning in both the meat mixture and in the enchilada sauce. Top with fresh minced cilantro or serve cilantro on the side

    Since zucchini is not at peak right now. So I MIGHT sub in " some" frozen & thawed cauliflower rice for "some" of the shredded zucchini.

    As written, this is a good recipe ...just BE VERY SURE TO squeeze the zucchini VERY well in several paper towels, after draining. Then add in garlic POWDER & some Italian seasoning to meat mixture & crust. I Also like to tightly roll up stacked leaves of fresh basil and cut into thin strips (chiffonade) Then top it on as a generous garnish . No wonder it is a contest winner ! Well Done !

    We love this "casserole"! We are on a low-carb diet, my husband and I, and have a craving for Italian food, especially pizza. This has solved our problem without busting the diet. After the first time I made it, I have changed it a bit, not in the recipe, but in the preparation. Since there are only 2 of us, I make the bottom "crust" in 2 8X8 inch pans, lined with parchment paper, partly up the side, and sprayed with cooking spray. I make half of the recipe in each, and cook it as directed. After cooling, I lift it out by the parchment, put both in a freezer container, and freeze until we are ready to use it. When we need a pizza, we take one "crust", thaw it in the 8X8 pan, and put the toppings on, cook it in the oven as the recipe calls for. It is almost as quick as a frozen pizza!

    I did as someone suggested, made half the recipe & put in 8x8 baking dish. I used Prego, and squeezed the zucchini with paper towels to remove more moisture. FABULOUS! Even my zucchini-hating hubby loves this! Will be making this again!!
