Press the cloves into the onion halves at random.
Place the ProZero, butter, garlic, bay leaf and thyme into a pan and add the onion halves over a medium heat.
Bring to the boil and then reduce the heat and allow to simmer for 15 minutes to let the flavours infuse.
With a slotted spoon remove the onion and bay leaf. Stir in the breadcrumbs and simmer for a further 5 minutes.
Allow to cool and serve.
