Start by adding the chopped tomatoes, garlic, fresh chillies (I left the seeds in for extra spice but you can remove if preferred) spices, a small handful of coriander and a large pinch of salt and pepper. Blend until combined.
Add the chicken breast into your slow cooker/crock pot, along with the olive oil and seasoned tomato mix. Stir to combine and cook for 3 hours on high, or 4 hours on low.
Once ready, use two forks to shred the chicken, then stir to evenly coat in the sauce.
Combine the creme fraiche/sour cream with a squeeze of lime juice, some finely chopped coriander and stir to combine.
Lightly toast your wraps and add a layer of the tangy creamy sauce. Then serve with a portion of chicken. Top with diced onion, fresh coriander, sprinkle of optional cheese and a squeeze of lime juice.
