Preheat your oven to 180°C.

Add the chicken breasts to a bowl and set aside.

Add the mustard, honey, lemon zest, garlic, 2 tablespoons of olive oil and sea salt to another small bowl, mix together well until combined.

Pour this mixture into the bowl with the chicken and toss together until the chicken is well coated.

You can now cook this straight away or allow to marinate in the fridge for 4-8 hrs.

Heat 1 tablespoon of olive oil in a large fry pan over a medium heat.

Add the chicken breast and cook on each side for 5 minutes until golden brown.

Pop the fry pan with the chicken into the oven and cook for a further 15 minutes, until the chicken is cooked all the way through

. If you have very large chicken breasts you may need to cook them in the oven for a further 5-10 minutes.

Remove from the oven and serve sliced with your choice of vegetables or salad.
