To make the chill put a large pan onto a medium heat. Add the oil and then the onion and pepper. Leave to cook for 5 minutes until softened then add the garlic and all the spices. Then add the mince, breaking it up and letting it brown and cook evenly. Add the tomatoes, the beef stock and kidney beans and leave to simmer for 10 minutes. Set aside.
To assemble use a round dish (ideally the same size as the tortillas) and layer chilli, tortilla, mascarpone, mozzarella three times until all the ingredients are used up.
