I love this recipe. I originally got it off a fitness forum a couple of years ago and when I used to contest prep for bodybuilding I must have eaten this at least once if not twice a week. I like it best with zucchini but you can also make it with eggplant. The method is the same for either vegetable.
Take 2-3 large zucchini and slice them lengthwise. Place on an oven tray. Grill zucchini in batches and set aside.
Chop up one small onion and in a non-stick skillet, cook in a little olive oil for 1-2 minutes. Add 400-500g of lean ground beef and cook until browned. Add 1 can of chopped tomatoes. You can also use pasta sauce if you wish; I used "Italian Tomatoes" which is just canned chopped tomatoes with italian herbs (basil, oregano etc.) Cook beef/tomato mixture until sauce is thick and bubbling.
Take 250g of low fat cottage cheese or ricotta cheese and blend until smooth. You can also make a batch of Bechamel sauce if you wish instead.
In a greased pan layer zucchini, beef then cottage cheese.
Finish with a layer of zucchini and then add 100g of a mix of low fat cheese and parmesan.
Place in an oven at 350 degrees F for about 10 minutes or until cheese has browned.
