My husband has a hearty appetite—our two kids never tire of pizza—and I grow lots of zucchini. So this tasty, tomatoey casserole is absolutely tops with us throughout the entire year. Once you've tried the recipe, you may even decide to grow more zucchini in your own garden next summer! —Lynn Bernstetter, White Bear Lake, Minnesota

"Excellent! Great low carb dish to satisfy cravings for pizza. Will be making this and changing up the meat/veggies to make different varities(this time I used ground beef,mushrooms and black olives. I also added seasoning to tomato sauce (red pepper flakes, garlic powder and Italian seasoning."

"This recipe is great; it's delicious and different. We tried it with sausage instead of beef first, and that was way too salty; that is not the fault of the recipe though. I add Italian seasoning to the sauce and cook the green pepper with the onion."

"My picky family liked this recipe. I made it as written, except that I added minced garlic when browning the ground beef and also used pizza sauce instead of Italian tomato sauce. I may try some other options next time, like adding mushrooms."

"Very good recipe!! I, too, added a bit more seasoning to the meat (oregano and garlic) but otherwise made as written. I tend to like my food a bit more spicy so thought maybe I'd add some dried pepper flakes to the meat the next time. Very good warmed up the next day, too!! I can't wait for zucchini season to make this again and again!!!"
