Place tomatoes in hot water (approx. 5 minutes), then briefly rinse in cold water and peel them. Break the spaghetti into pieces approx. 8 cm in size, cook in salted water until firm to the bite and allow to cool.
Mix the tuna oil, mayonnaise, Tabasco, soy sauce, kebab sauce and spices and season to taste (slightly hot). Cut the peppers, tomatoes and onions into small cubes and add to the sauce. Crumble the tuna in, mix in the spaghetti. Season again briefly and let steep for 24 hours.
