Gather your equipment and prepare your ingredients.
In a small bowl mix together the Ground Cumin, Ground Coriander, Garlic Granules, Oregano, Sea Salt, Chilli Powder, Smoked Paprika, Cocoa Powder, Black Pepper, Ground Cinnamon. This is your Chilli Spice Mix.
Put all the remaining ingredients including Sweet Potatoes, Celery, Onion, Aubergine, Courgette, Red Bell Pepper, Red Chilli, Chopped Tomatoes, Black Beans, Mixed Beans, Tomato Purée, Coconut Aminos and the Chilli Spice Mix into the pot of the slow cooker and give everything a good stir. Put the slow cooker on high and let the chilli cook for 4 hours. Don't be tempted to remove the lid. It will take some time for the Chilli to get back up to temperature which will increase the overall cooking time.
After 4 hours, treat yourself to generous portion and enjoy!
