Season the chicken with salt and black pepper. Heat some oil in a large pan over a medium to high heat. Cook the diced chicken until there are no more pink bits.
Add the garlic, chilli paste, and oregano and cook for a further minute.
Now add in the tinned tomatoes, tomato paste, balsamic vinegar, and chicken stock. Bring it to a boil.
Add in the pasta. The sauce will be very watery, but don’t worry, the pasta will absorb it as it cooks.
Turn it down to a simmer, and then cook for 10-12 minutes, stirring often, until the pasta is cooked, and the sauce has thickened. If it goes too dry add a splash more water or stock.
Stir through the basil, and mascarpone until you have a creamy glossy sauce.
Dish it up, and finish with some grated Parmesan, if you like. Enjoy!
