@contentandwell Gosh, I must confess I don't measure anything! That's probably a curse to some [thinking @jakedduck1]. I start with about 1.5 pound ground turkey. I don't eat beef hardly at all. Ground turkey is my go-to along with chicken and fish. Handful or more of diced celery and another of the same amount of diced onion, all fresh. Cup to cup and a half of pasta sauce. If you don't have that try salsa or tomato sauce. Oatmeal about 1 cup or so, helps bind things together rather than breadcrumbs, and will give you a solid loaf. One or two eggs. If you are using veggies you can take and mash them up if you want. Spices I just keep shaking the shakers until it looks like enough. I am fond of pepper, and salt free multi spices like Mrs. Dash. Garlic either fresh or minced add a little bit of a taste component, too. Everything gets mixed well together using my hands and baked. Like I said you can be very creative with it!
