2 eggs
1 small onion, minced
2 pounds ground beef
1/2 cup milk
1 teaspoon salt
1 tablespoon chopped celery
1 cup cracker crumbs
1 1/2 cups ketchup
1/4 cup prepared yellow mustard
1/2 cup distilled white vinegar
3/4 cup brown sugar
Preheat an oven to 350 degrees F (175 degrees C). Beat the eggs in a mixing bowl. Add the onion, beef, celery,milk, and salt; mix well. Sprinkle in the cracker crumbs and mix until evenly combined. Form the mixture into 40 meatballs and place into a 9×13 inch baking dish; set aside. Whisk the ketchup, mustard, vinegar, and sugar in a bowl; pour over the meatballs. Bake in the preheated oven until the meatballs are no longer pink in the center, about 1 hour. Enjoy!
