Preheat the oven to 350 degrees F (175 degrees C).
Mix meatless ground beef, bread crumbs, onion, egg, garlic, basil, curry powder, ginger, paprika, salt, and white pepper together in a bowl.
Form mixture into 16 balls and lay out in a baking dish.
Bake in the preheated oven until browned, about 15 minutes.
While the meatballs are baking, heat oil in a pan over medium-high heat. Saute bell pepper, carrots, and celery in the hot oil, stirring constantly, until translucent, about 7 minutes. Add crushed tomatoes, bay leaf, and salt; cook over low heat for 10 minutes.
Transfer the cooked meatballs, including any pan juices, to the sauce and stir, making sure to coat evenly. Cook over low heat for 5 minutes. Serve hot.
