Heat 1tbsp of oil in a large pan, add the onion and cook for about 5 minutes until the onion starts to go translucent. Add in the garlic, stir and cook for a further minute. Add in the rice and stir until the oil has coated the rice. Add in the wine and stir. Wait for the wine to almost fully absorb (stirring regularly) and then add the stock a ladle at a time - ensuring each ladle has almost fully absorbed before adding the next. Ensure you stir regularly. This should take approx 15-20 mins.
Once you've used up all the stock, have a taste of the rice. It should be softer, but still have a bit of a bite to it . If the rice is still far too hard, you can add in a ladle or so of hot water from the kettle. Once the risotto is cooked, turn the heat down to very low.
Heat 1 tsp of oil in a small frying pan and add in the halloumi. Cook on a medium-to-high heat for 2 minutes on each side until golden brown.
Whilst the halloumi is cooking, go back to your risotto. Add in the parmesan, lemon juice and salt & pepper. Give everything a good stir then turn off the heat and gently stir in the spinach, watercress, basil and parsley. Divde the risotto between 2 plates and top with the fried halloumi.
Serve sprinkled with lemon zest, a squeeze of lemon juice and some freshly ground black pepper.
