In a large bowl, mix together the ground beef, onion, eggs, salt, pepper, and garlic powder. In a separate dish, soak the 3 pieces of white bread in milk. Tear apart and add to the mixture in large bowl. With your hands, mix together well. Shape in 1-2 inch balls, then roll each one in flour. Heat bacon grease in fry pan to 350°. Place meatballs in pan and cook until golden brown on each side.

**A special word from Grandpa:
"These meatballs are best when served over noodles with lots of butter (no tomato sauce). I always use bacon grease when cooking my meatballs and find this gives them that special flavor. If you're worried about your cholesterol, go have a salad."
