Preheat oven or air fryer to 200C. Chop the parsnip, onion and courgette into approx 2cm cubes. Peel the garlic cloves and crush under the blade of a knife. Place all the vegetables onto an oven tray (or air fryer basket), drizzle with olive oil and season with salt and pepper. Stir to coat. Cook 15-20 minutes until nice and crispy.

Top with the tomato paste and half the grated cheddar cheese. Add the roast vegetables, more cheese and the chicken. Dot the cream cheese all over the top.
