Heat the oil in a large casserole dish or lidded frying pan.
Peel and chop the onion, and peel and crush the garlic cloves. Fry over a gentle heat for 3-4 minutes until they are starting to soften.
De-seed and chop the red pepper and green chillis - the pepper can be in quite large chunks, and the chillis should be fairly small. Add to the frying pan and cook for a further 3-4 minutes.
Add the vegan mince and cook for 3 minutes
Add the lentils and kidney beans to the pan, followed by all the remaining ingredients, and season with salt and black pepper.
Bring to the boil, then reduce to a simmer and cook for 15-20 minutes until the liquid has reduced to a thick, glossy sauce. If it is looking too dry, add a little more water whenever it needs it.
Serve your chilli with rice or fajita wraps, nachos, jacket potatoes, vegan cheese, dairy-free sour cream, guacamole, fresh coriander and a squeeze of lime, or anything else you fancy!
