To make a green spaghetti, take one large courgette per person, and use a spiralizer to shred it (or use a potato peeler to create ribbons). Stir fry in olive oil, coconut oil or butter with onions and garlic. That's it. You're done. Easy.
Next, make a nice comforting sauce, inspired by your favourite cuisine:
Italian ~ use olive oil to fry some garlic and onions, add chopped fresh tomatoes and parsley. And you could add some minced lean meat.
Mexican ~ mash a ripe avocado, add yogurt or mayonnaise then a squeeze of lime juice, a hint of chili and some chopped fresh coriander.
Thai ~ add a big spoonful of Thai curry paste to coconut milk with some peas, spring onions, peppers and fresh basil then simmer until thick.
...and Estelle's favourite ~ add some bacon or pancetta as you stir fry the noodles, then whizz an avocado with lemon juice and pour over the top.
