Slice the chicken breasts in half lengthways to make two thinner fillets.
Mix the wholemeal flour with salt and pepper, then coat the chicken breasts in the seasoned flour.
Heat some cooking oil in a large frying pan over a medium to high heat. Cook the chicken until it’s golden on both sides. Once golden, remove it from the pan and set aside.
In the same pan, add the onion and cook until it softens.
Chuck in the garlic and cook for a further minute.
Pour in the chicken stock and stir through the half-fat crème fraiche. Stir well and bring to a low simmer.
Stir in the sun-dried tomato paste, oregano, and parmesan, then get the chicken back into the pan.
Simmer for a few minutes, until the sauce thickens, and the chicken is cooked through.
Stir through the fresh basil right before serving, then taste for seasoning. Dish it up and enjoy.
