Preheat the oven to 200 degrees Celsius (390F)
On a large baking sheet add the chopped bell peppers, onions, cherry, chorizo, tomatoes and olive.
In a bowl whisk together the olive oil, crushed garlic, paprika, oregano, vinegar, salt and pepper. Pour 2/3 of the sauce over the veggies and toss with your hands to ensure everything is well coated. Place the chicken pieces on top of the veggies and brush with the remaining sauce.
Bake in the oven for 30 minutes, remove from the oven half way through cooking and spoon some of the sauce from the bottom of the dish over the chicken and veggies before returning back to the oven to bake.
Check the chicken to ensure it's no longer pink. Sprinkle the veggies with chopped parsley before serving.
