Start Boiling Spaghetti along with salt in around 2 liters of water till reaches Al Dente ( it is a stage when the pasta is firm to bite). It took me 9 minutes of cooking to reach Al Dente.
Strain 1 Cup of Water from the Pasta and keep it for future use and discard rest of the water.
Drizzle around 1 Tsp. Olive oil over the Pasta and mix lightly.
Make a paste of Tomatoes, Chop Garlic and Onions separately.
Heat 1 Tbsp. Olive Oil in a wok and add chopped Garlic in it and cook till aroma comes from the mixture.
Add Chopped Onions and cook until those turn light pink in color. Don’t over-fry Onion.
Now add Tomato Puree and cook until tomato mixes properly and there is no raw smell in the mixture.
Now add salt, Crushed Red Chilli, mixed herbs, Basil Leave and give the mixture a light mix.
Add some Tomato ketchup to the mixture.
Add Crushed Fish pieces to the mixture and cook for 1 more minute. You can keep few pieces of Grilled Fishes for garnishing.
Add 1 Cup of Pasta boiling Water to the Sauce to make it a bit runny and bring it to boil.
Finally, add Boiled Spaghetti and toss properly to mix Spaghetti with the sauce.
Switch the Flame off and Serve Spaghetti with Grilled Fish in Red Sauce after garnishing with Grilled Fish chunks.
Notes
More Chili Can be added while making the Sauce. Instead of Dried herbs, fresh herbs can be added for extra flavor. Instead of Pureed Tomato, chopped tomatoes can also be used
