Heat oil. Sautee the onions for 1 minute. Add tomato paste and fry until it dries out. Stir in bay leaves and spices.
Add 1 cup of water to the mix and then add meatballs. Simmer for a minute and then add chopped red and green bell peppers. Stir again.
Add chopped kale and stir. Allow heat to soften the kale. Set this mixture aside.
For pasta, bring about 6 cups of water to a boil and add the pasta with 1 tablespoon of salt and cook for 8-10 minutes. Adjust salt according to taste.
Drain the pasta and reserve ½ cup of starch water.
Transfer pasta back to the pot and add in the mixture prepared previously to the pasta. Combine thoroughly for best taste.
Add the starch water if needed for thicker sauce texture.
