What can I cook for dinner?

Onhand have pork sausages, stewing beef, onions, only 2 small potatoes, pasta, rice, couscous, carrots, frozen peas, yoghurt, tinned tomatoes, and a range of herbs and spices including chilli, harissa and ginger but no garlic. I feel like something a bit different... Won't be home until late, so needs to be fairly quick to prepare.
