Soak rolls in water. Peel and finely dice onions. Squeeze out the buns well. With minced meat, egg, 1 tablespoon of tomato paste, approx. 1⁄3 of the onions, 1 1⁄2 tsp. salt and pepper each, knead well. Form about 40 small balls with moistened hands, dipping your hands into cold water again and again.
Gradually heat the oil in a large pan. Fry the meatballs in portions for 5-6 minutes and remove. Sauté the rest of the onions in the frying fat. Stir in 1 tbsp. tomato paste and 1 1⁄2-2 tsp. Garam Masala and sauté briefly.
Put the meatballs back in the pan. Deglaze with wine and 300 ml water. Bring to the boil and braise open for 15-20 minutes, stirring occasionally.
Meanwhile cook the spaghetti in 4-5 l boiling salted water (approx. 1 teaspoon salt per litre) according to the instructions on the packet. Wash parsley, shake dry, pluck off leaves and chop coarsely.
When the sauce of the meatballs has thickened, season with salt and pepper. Drain the noodles. Arrange everything and sprinkle with parsley.
