Preheat oven to 350F and line a baking sheet with parchment paper.
In a large bowl, combine ground chuck, breadcrumbs, eggs, chili sauce, Worcestershire Sauce, onion and salt. Mix until all ingredients are incorporated but do not overwork the mixture or the meatballs will be tough.
Form into 1½ inch meatballs and place on the prepared baking sheet. Leave at least 1-inch space between meatballs.
