Blend the tin of chopped tomatoes with the onion in a food processor until smooth.
In a casserole over medium heat, lightly toast the rice for 5 minutes in oil. Once rice is toasted add chilli and garlic and toast for 2 more minutes.
Pour your tomato mix into a pan and heat until simmering. Add chicken stock, cumin and salt. Stir through and cover. Leave to simmer on a low heat for 15 minutes.
When rice is done simmering, remove from heat, stir and place aside for 10 minutes with the lid on.
Before serving add the coriander and juice from one lime and serve!
