Boil the pasta according to instructions on the packet (add the peas and other greens too, so you can cook them with the pasta and save energy/time/washing up)
Meanwhile, scoop avocado flesh out of the skins into a bowl and mash with a fork until a smooth paste forms (the riper they are the easier this will be)
Add the lemon juice, basil, salt + pepper and nutritional yeast, and mix well
Drain the pasta and peas once cooked and take off the heat
Add the avocado pesto, to the pan and mix well
Serve up and scatter over the pine nuts and fresh salad and chickpeas if you like
