* Note - Chipotle in Adobe sauce are available in most big supermarkets or gourmet delis. They are the flavour hero of this dish and give it a little heat and a beautiful smokey flavour (obviously the more you add the spicier it becomes - 1 chili pepper is still mild, 2 chili peppers add a tiny amount of heat). Once you've opened the can, store leftovers in an airtight glass jar in the fridge. They last forever this way and trust me, you will make this meal again! If you happen to have the paste (so no visible chili peppers), then 1tsp is about the same as 1 chipotle chilli.
If you don't have chipotle you can sub with a heaped teaspoon of cumin and smokey paprika. This option will have no heat at all. If you only use just one chipotle, perhaps add ½ teaspoon of cumin and smokey paprika too.
Place the garlic, tomatoes, chipotle, almonds, celery, stock and sea salt in a food processor or high speed blender and process until smooth. If using a Thermomix, 1 minute, speed 7.
Put your chicken thighs into a large pot with the black beans and sauce, cover and simmer over a low to moderate heat for approx. 30 minutes. If using a Thermomix, add the chicken and black beans to the sauce and cook 30 minutes, temp 90, reverse lowest speed.
To make the guacamole, mash the avocado and mix with the lime juice and seasoning.
Once the chicken is cooked, mix through the coriander and serve with the guacamole (and any of the suggestions below).
