Make the spag bol. Fry beef mince until well browned. Season well.
Add in the onion, carrots and celery and sweat out for 3 minutes.
Add in the tomato puree, the Worcester sauce and the wine and reduce.
Add in the chopped tomatoes, and 1 tin's worth of water.
Simmer for 1 hour until reduced and cooked nicely. Chill
Cut the paninis in half lengthways and stuff with the bolognese. Add a generous portion of cheese and close.
Mix together the chopped garlic, butter and parsley in a bowl and slather on top of the Panini, making little insertions into the bread as you go to let the garlic butter permeate.
Place in a Panini machine until the cheese has melted.
