I found and made a wonderful lentil chili recipe on the web but when I wanted to make it again I couldn't find it. This is my attempt to recreate it. It is a substantial chili that your guests might not realise has no meat in it (I do eat meat but not every day). Vary the garlic and chili to your taste - I just happened to have some harissa to hand. Cumin gives a nice warm note. It is one of those "even better next day" dishes. This makes quite a lot but I do have quite a large slow cooker. If you didn't have a slow cooker I guess you could simmer on the hob for 90mins or so?
