Gently mix together ground burger, parsley, garlic, eggs, breadcrumbs, wine, a good pinch of salt and pepper. Let sit for about 30 minutes.
Shape into small meatballs about one inch round by rolling between your hands.
Spread out flour on a rimmed sheet pan and roll your meatballs all over, lightly coating in flour.
Heat oil in a heavy bottom fry pan over medium high heat. Working in batches, add meatballs to pan and cook about 5 minutes turning frequently.
Once browned, transfer to a bowl or plate and continue cooking the rest. It's OK if they are not completely cooked through as they will finish cooking in the tomato sauce.
While they are cooking, grind your saffron threads and mix into water. Set aside.
Once all meatballs are browned, combine meatballs and tomato sauce in pan.
Pour in saffron liquid and gently stir to combine. Let simmer about 10-20 minutes. Taste and add additional pepper and salt if needed.
Serve with sliced rustic bread to mop up the tomato sauce.
