Firstly to make the jerk paste add to a food processor half of the onion, the garlic cloves, the ginger, the chilli, spring onions, olive oil, lime juice, soy sauce, vinegar and the spice blend.
Process this until smooth and set aside.
Dice the other half of the onion and fry off until soft in some olive oil.
Add the jerk paste and mix well.
Next add in the tomatoes and leave the mix to simmer for 15 minutes.
Lastly add in the lentils with their juice from the can and cook this down until it thickens.
Serve up with some rice and a squeeze of lime juice over the top.
