I'm really bad at measuring ingredients when I "try" new things, so I will give you approximates and you can adjust to your families likes or dislikes. This is an original recipe by Mom and I.
4 lbs. hamburger
1/2 cup shredded onion
1 cup shredded carrots
1 cup crushed roasted vegetable ritz crackers
salt and pepper to taste
Mix together all ingredients with your hands. GET MESSY! Using an ice cream scoop, place balls on a tin foil lined cookie sheet. Bake for about 25 to 30 minutes in a 400 degree oven. Let meatballs cool and place in gallon sized freezer bags until ready to use. Freeze.
Place as many meatballs as you need for your dinner onto a cookie sheet and bake to just heat through. ENJOY!
This made enough meatballs for us for about 4 meals for about 4 people, but different family needs could mean more or less for your family.
