Heat the oven to 180 Celsius.
Cut the sweet potato in half lengthways and place onto a baking tray, sprinkle with a little olive oil and salt and pepper and bake till cooked and golden in colour.
Drain the lentils and set aside.
When the sweet potato is cooked and cooled, remove the skins and lightly mash with a fork but keep it kind of chunky in texture.
Heat the oil in a largish frypan over medium heat. Add the onions, garlic and capsicum and stir and cook for around 5 minutes.
Add the spices, cumin, coriander, paprika and chili flakes and cook for a minute or till the aromatic.
Add the lentil, kidney beans and sweet potato to the pan along with the can of tomato soup and cook gently till combined and thickened slightly. Around 5 minutes or so.
Serve with guacamole, corn chips, shredded lettuce, chopped tomatoes, lime wedges and soft fluffy rice. Whatever your fancy.
