In a large mixing bowl, mix the pork mince, 1 pinch of salt and pepper and 2 teaspoons of mixed herbs well.
Heat the oil in a sauce pan (an enamalled cast iron pan is also fine).
Take a small handful of the mince meat, roughly 1 1/2 tablespoons and roll into a ball. Repeat until all the mixture is used up.
Gently place the meatballs into the frying pan. As they start to brown turn them over. They should be a fairly dark brown to make sure you get the flavour of the meat. See the instagram video as an idea, it should take roughly 10 minutes,
Add the chopped tomatoes, then fill the empty tin with tap water and add that too.
Crumble the stock cube in, season with salt and pepper and add the chilli flakes and sage leaves.
Simmer on the hob for an hour, or the pressure cooker for 30mins, or the slow cooker for at least 2 hours.
