To begin making Spaghetti Pasta Recipe in Basil Pesto Sauce, fill a large pot with water and bring it to boil. 

Add the pasta to the boiling water along with some salt and cook the pasta in the boiling water.

Cook until the pasta is al dente (just cooked with a firm bite) , this will take about easy 7-9 minutes. 

Drain the boiled pasta in a colander and rinse with cold water. Rinsing with cold water is an important step to stop the cooking process of pasta so it will continue to have a firm bite and remain "Al Dente".

Once done,  drizzle some olive oil on top and set aside until required.

In to a blender, add basil, sunflower seeds, garlic, salt, sugar, parmesan cheese and olive oil. Blend all of the ingredients together to get a smooth basil pesto without adding any water.

Into a wok, add 1 tablespoon of oil, add the red bell peppers and saute until lightly softened and roasted. Add the zucchini, sprinkle salt and saute until cooked. Finally add the pesto, cooked spaghetti and black olives and sauté on high heat until all the pasta it coated with the sauce, for about 4 to 5 minutes.

Check the salt and pepper and adjust to suit your taste.

Serve the Spaghetti Pasta in Basil Sauce topped with chili flakes and Parmesan Cheese immediately for dinner or even a Sunday brunch.
