When making meat loaf, what do you add for filler?

This is interesting, I have never heard of using oatmeal.. I have always wanted to try a different "filler", very cool, what does it do to the flavor? Does it make it too sticky? I think I will try this! I have always used either bread crumbs or like another poster said, bread soaked in milk. Very good ideas!

I use oatmeal & 2 eggs in my meatloaf. It holds it together really well. I luv makin meatloaf. it's so delicious. my fam loves it!

Its not something I make very often, (I'm more of a mock-haggis sort of girl if I'm looking to use up meat), but I would use oatmeal, an egg, absolutley masses of black pepper, a finely diced onion and a small chilli and some mixed herbs. Possibly barley if I wanted something really robust, but mostly oatmeal I think.

I use onion soup mix. Egg and plain oatmeal get thrown in too. But my sauce is always different. Sometimes it is salsa. Sometimes its ketchup or BBQ sauce. Whatever I have handy or am in the mood for.

I like to use Italian flavored bread crumbs and also throw in a pack of lipton powder mushroom and onion soup. They combined really give it a great flavor

i wet 2 or 3 pieces of bread w/milk & add it to my meat. it makes it nice & soft.

I do pretty basic ones. Besides the obvious meat and eggs I add in diced carrots and onions and sometimes potatoes. For the other stuff I sometimes use oatmeal but have found that I prefer cornmeal and instant potato flakes better.

I don't really make meatloaf - i think its a US thing? If I get sausage-meat ever I use it to make sausage rolls, either flavoured with leeks and cheese or sometimes with tomato and chilli! I would guess that breadcrumbs would be best as they would absorb some of the fat.

I use bread crumbs, and of course and egg. I also like to add chopped onions, garlic and green pepper. The veggies not only add flavor, but help to keep it moist.

I usually use a piece of bread. I tear it up very small though. It's what my mother used to do, and is she is, was a pretty good cook. My huby loves my meatloaf he thinks it's really delcious. I didnt think he liked anything better than salmon, but I think meatloaf is it.
