To a large pan, add the chorizo along with the olive oil. Gently fry over a low heat for around 6 minutes, allowing the fat to render and the chorizo to crisp up.
Next, remove ⅓ of the crispy chorizo and set aside. Add the onion and season with salt and pepper. Gently fry over a medium heat for around 4 minutes,, stirring frequently. Then add the tomato puree and continue to fry for a further 3 minutes and add the garlic to fry for the last minute..
Once the tomato paste has darkened in colour, add the arborio rice into the pan and stir to coat. Deglaze the pan with the vinegar/water to mix, then add 2 ladles of chicken stock. Stir frequently.
When the stock has fully absorbed, add another 2 ladles of chicken stock. Continue this process, until you have around 150ml of stock left.
After around 20 minutes of cook time/ when you have 150ml of stock left, add the spinach, cooked chicken thighs, parmesan and cream. Stir to combine and slowly pour in the remaining stock.
When the spinach has wilted and the risotto is fully cooked, top with fresh chives and the crispy chorizo. Season to taste, serve up and enjoy!
