-in-law uses 1 lb GROUND TURKEY, OATS, 1/2 SHREDDED CARROT, 1 1 CAN TOMATOS, 1 CAN TOMATO SAUCE, 1/2 SHREDDED ZUCCINI, GARLIC, ITALIAN SEASONING, SALT, PEPPER, and of course an EGG. I don't want to give away the secret amount, but I will say that if you leave any of these ingredients out, it will not come out moist.
Your loaf NEEDS the TOMATOES and NEEDS the tomato sauce---use most of the 15 oz. can, but leave 2 inches for pouring over the top. The carrots add a bit of moisture, and also add a bit of sweetness. Of course, add a tad of SALT.
The Italian seasoning adds a bit more interest to the flavor, and keeps me wanting MORE!!!
The oats are a great way of getting whole grain wholefoods in your diet without any added flavor...it also helps hold the loaf together.
When you put your concoction into a pan, mound it towards the middle of the loaf; this will keep your loaf from being too thin and makes for a nice presentation.
