I am one of those people that loves meatloaf...it is pure comfort food for me, so once I got my stock of gluten-free oats I knew I was going to be making meatloaf. Here's my Mom's recipe, modified slightly to make it dairy free as well:
1 lb ground beef
1/4 C ketchup
1/2-3/4 C gluten-free rolled oats
1/2 t onion powder
1/2 t salt
1/4 t black pepper
Mix together and put in a greased bread pan or in muffin tins (I like meat muffins, because they cook a lot faster and they are already in individual servings). Cook at 350 degrees for 50-60 minutes for a loaf or 20-30 minutes for muffins.
