Slow Cooked Spanish Beans (v)

This was so delicious I can't even begin to describe it. What the slow cooker does to tomatoes is amazing. Me like. Lots.

For 4-6 portions you need:
1 medium onion, chopped
2 cloves garlic, crushed
1 tin tomatoes
1 tin chickpeas
1 tin butterbeans
1 tsp smoked paprika
1 tsp dried oregano
1 tsp dried and chopped ancho chillies
1 tbsp olive oil

Fry off the onion and garlic in the oil for 4-5 mins. Put everything into the slow cooker and cook on low for 8-10 hours. Sigh in contentment.
