Healthier Italian Spaghetti Sauce with Meatballs

Combine 454g ground beef, 50g breadcrumbs, 1 egg, 15g grated cheese, minced garlic, salt, and black pepper; form into 24 meatballs.

Heat 46g olive oil in a large pot over medium-high heat; brown meatballs in batches until golden, about 3 minutes per side.

Remove meatballs and set aside. In the same pot, gently cook 150g minced onion and garlic over low heat until translucent, 5 minutes.
