This is one of my very favourite recipes, sweet potato chilli.
Cut up 3 large sweet potatoes into 1 inch chunks and part boil. Crush 2 cloves of garlic, chop one red onion and soften in olive oil. Add 1tsp chilli powder, 1tsp of cumin, 1tsp of caster sugar and mix.
Add 2 tins of chopped tomatoes, 1 tin of black eyed beans, 1 tin of kidney beans and the part boiled sweet potato. Bring to the boil then simmer for 20 mins.
Serve with rice and sour cream.
