Heat oven to 200C/180C fan/gas 6. Put all the veg for the bake except the garlic in a large bowl and add 1 tbsp olive oil, then carefully turn everything over with your hands so the oil adds a very thin coating. Lightly oil the tray as well if you are worried about things sticking.

Arrange the veg in piles on the tray, or scatter it all over if you prefer. Add the garlic halves and the chicken, sitting the chicken on top of the veg. Season well and bake for 40 mins then, if the chicken skin is still pale, either turn the oven up or turn it onto the grill setting, and cook or grill until it is nicely browned.

Meanwhile, make the pesto. Whizz the kale, garlic and pistachios until everything is finely chopped. Add the parmesan, lemon juice and olive oil and whizz again. Add a splash of water to loosen. Any left over will keep in a jar for up to three days in the fridge. Serve the chicken and veg with the pesto spooned over.
