The perfect parsley and pea pesto pasta.
Put all of the ingredients in a food processor. (Reserve 1/4 cup of the peas to garnish the pasta). Blend until smooth. Taste for salt and adjust seasoning.
Bring a large pot of water to a boil. Season with 2 tsp of salt. Cook the pasta as per the package instructions, minus two minutes. (Reserve 1/2 cup of the pasta water just in case you need to loosen your pesto sauce).
Put the pesto in large saucepan or frying pan. Use a slotted spoon to transfer the cooked pasta to the pan. Add the 1/4 cup peas. Stir for two minutes and serve.
