Defrost the fish by covering the pack in just boiled water. Set aside.
To make the salsa, combine the diced tomato, onion, half of the coriander and a pinch of salt and pepper. Add the juice of half a lime and stir to combine.
To make the refried inspired beans, pour the contents of the can (including the juices) into a blender cup along with the ground cumin and a pinch of salt. Roughly blitz for a couple of seconds.
Pour into a pan over a medium/high heat. Also add a can’s worth of water and a beef stock cube into the pan. Simmer, stirring occasionally for 8 minutes, until it thickens to a dip like consistency.
During this time, cook your rice according to the packet instructions.
Pat the defrosted fish dry with a paper towel, then evenly coat with Cajun seasoning. Fry in a non-stick frying pan with rapeseed oil for 3-4 minutes on each side.
To the cooked rice, add the remaining half of the coriander and season with salt. Fluff the rice to incorporate the coriander.
Divide the elements of the burrito bowl into 5 containers. I used a container with compartments which makes it easier to separate the salsa when reheating.
