Spicy slow cooker chilli con carne

I managed to put this together in the 30 minutes that Sophie napped yesterday - yes!

Preheat slow cooker. Dice an onion. Fry with a little oil and 400-500g minced beef until the beef is browned. Transfer to cooking pot and add a chopped red pepper, four sticks of chopped celery, a tin of chickpeas, a tin of kidney beans, and generous sprinklings of hot chilli powder, ground cumin, ground coriander, and dried basil. Cook for 4-5 hours on high, or 6-7 hours on low. Eat with rice, tortillas, or jacket potatoes.
