Spiralise the courgette and divide onto two plates. Pop the frozen peas into a sieve, then run them under hot water to defrost.
To make the kale pesto
Pop the nuts into your food processor and blitz for a minute until broken down, then add in the rest of the ingredients. Blitz again until smooth and creamy.
To serve
Top the courgetti with the peas, kale pesto, avocado, and walnuts. Squeeze some lemon juice over everything and enjoy.
