In a liquidizer, puree half the blackberries with the red wine vinegar until smooth, then pass through a fine sieve to remove the pips.
Pour the blackberry puree into the pan with the reduced red wine and cook over a medium heat until reduced to 200ml – about 15 minutes. If the sauce becomes to thick add a splash of beef stock to thin as required.
Add the cooked pork to the blackberry sauce along with a knob of butter and the remaining blackberries.
When the greens have wilted fold in the toasted almonds. Spoon the greens onto four warm plates then top with the pork and surround with the blackberries and their sauce.
