1. Cook spaghetti as per packed instruction in salted water in a large saucepan. Once cooked as  per your preference, drain in a colander.
2. Rinse with cold water and toss gently in a teaspoon of olive oil. Reserve 1 Cup of boiled  pasta water.
3. Heat olive oil in a pan. Add pasta sauce and cook for a minute. Add the boiled spaghetti, salt  and seasoning.
4. Toss spaghetti in the sauce so that it gets coated nicely. Add 1/2 Cup of reserved boiled  pasta water and stir to combine.
5. Cover the pan with the lid and cook for 5 minutes for spaghetti to absorb the sauce.  Open the lid, add fresh basil leaves and olives. Pack for the school lunchbox.

Enjoy your meal!
