Preheat the oven to 200C fan.
Add the chicken breasts into a bowl, then sprinkle in the salt, pepper, garlic granules, paprika, and oregano. Mix the chicken until each piece is nicely coated in the spices.
Bake it for 10 minutes.
Meanwhile, add the honey, wholegrain mustard, Dijon mustard, chicken stock, and cornflour into a bowl and whisk until smooth.
Take the chicken out from the oven and pour the sauce all over each bit of chicken.
Bake it for a further 20 minutes.
Take it out, spoon some of the sauce over each chicken breast, then leave to stand for a couple of minutes. Sprinkle over some chopped parsley if you’d like.
Dish it up with potatoes or rice and enjoy.
