Marinade the chicken in the chipotle paste and leave in the fridge whilst prepping everything else
Peel the onion and slice in half. De-seed the bell pepper and place both on an oven tray. Bake at 200C/400F for 30 minutes or until slightly charred.
Remove the skins from the bell peppers
In a non-stick frying pan with no oil, toast the spice mix for a minute util fragrant.
Add the spices, bell pepper, onion and tinned tomatoes to a food processor and blend until smooth.
In a thick bottomed casserole pot, heat some oil and fry the chicken until browned on both sides. Add the sauce and allow to cook together for 20 minutes.
Using two forks, shred the chicken, season with salt and pepper and leave to cook for a further 15-20 minutes.
Meanwhile, make your sweetcorn salsa by mixing the corn, cherry tomatoes, diced shallot, lime juice and fresh coriander in a bowl.
Now prep your shredded chicken tacos!
Lay the soft taco shells on a baking tray and scatter over some grated cheese before adding two tablespoons of the shredded chicken to each one.
Fold and close the tacos before baking them in the oven for 10-20 minutes until the outside is crispy and the cheese is melted.
Serve drizzled in sour cream and with the sweetcorn salsa on the side
