1/2cup(5 ounces, 150 grams) tomato paste diluted with 1 cup (225 milliliters) water
Instructions
For the meatballs:
Mix the eggs, torn bread, onion, salt, pepper, soy sauce, and parsley in a food processor for 30 seconds, or until smooth.
Transfer the egg mixture to a bowl and mix in the raw meat with your hands or a large fork until smoothly blended. Set aside for 30 minutes.
With wet hands, shape the mixture into patties or balls.
Put the seasoned flour on a piece of parchment paper and dip each ball into it. Shake off any excess flour.
Heat the oil in a heavy frying pan for 4 minutes, put in the meatballs, and fry steadily until they are a rich brown color on both sides (you may need to do this in batches).
Transfer to a plate using a slotted spoon, leaving behind any oil in the pan.
Now make the sauce:
In the same pan, sauté the onion until golden. Add all the remaining ingredients and simmer for 5 minutes.
Place the meatballs in a casserole dish or Dutch oven, pour in the sauce, and cover. Either simmer on the stovetop for 30 minutes or bake in a slow oven at 300˚F (150˚C) for 45 minutes.
