For the crispy sage leaves, heat a frying with 1/2tbsp oil, pop in the leaves and fry till crisp. Take out and put onto kitchen roll. The oil can now be used to fry the onions.
For the sauce: Fry the onion in the sage infused oil till soft and translucent, add in the garlic and cook for a further 2 mins. Once the onion’s cooked bung it in to a blender with the remaining sauce ingredients and blitz till smooth.
While the onions are frying, get a large frying pan on the hob and cook the mushrooms in 1 tsp of oil till nicely browned, about 8 mins. Season with a little salt and pepper once cooked. The key is to not crowd the pan so they don’t end up stewing, so use the biggest you've got.
Add the sauce and spinach into the mushroom pan and heat till hot and the spinach has wilted.
Take the sauce off the heat and whack in the courgetti. Stir till coated.
Tip into bowls, sprinkle with pine nuts, sage and parmesan.
Best eaten straight away.
