I'll have to try your recipe OKSglad...I've never put potatoes in mine..
3 lbs ground beef
3 eggs
6 slices white bread cubed
1 med sized onion chopped
1/2 to 3/4 cup milk or 1/2 & 1/2
4 cloves garlic
1/2 cup fresh chopped parsley
sprinkle of oregano/basil
I/4 cup parmesan cheese
In a blender crack 3 eggs , add milk, and the rest of the ingredients except the bread & cheese...blend then pour over the cubed bread then add & mix with the ground beef.. add cheese is optional...if the mix is too soft add breadcrumbs.. I roll them up into balls and bake them in the oven.. My oldest grandson call them "Gramballs" because they're the best meatballs grandma makes..
