Boil water in a deep pot and cook the pasta according to packet instructions. Drain and set aside.
Add all ingredients under “pesto” except the olive oil into a blender and begin to blend. Whilst blending, slowly pour in the olive oil and blend until your desired consistency. I personally like my pesto quite chunky, but it’s up to you!
Add olive oil into a hot pan and heat for 1 minute. Add onion, garlic and chilli to the pan and cook for 2-3 minutes until the onion is translucent.
Add prawns into the pan and cook for 2-4 minutes (or until fully cooked).
Add the cooked pasta into the pan and stir. Add 4 heaped tablespoons of the pesto into the pasta and stir through. If you want more – add more!
Serve with some fresh parmesan cheese!
