Preheat oven to 180°C. Put oil in a large, wide heavy-based ovenproof saucepan with lid. Add sweet potato, celery, capsicum, onion, garlic and tomato paste. Stir, then add paprika, fennel seeds, bay leaf and chilli. Toss well to coat vegetables, then season. Roast for 30 minutes, stirring halfway through, or until vegetables begin to brown.
Remove from heat and stir in stock, beans, tomato and oregano. Cover with lid and return to oven. Roast for a further 35 minutes or until vegetables are almost tender.
Gently stir in prawns, cover with lid and return to oven for 10 minutes or until prawns are cooked through. Garnish with extra oregano and serve with sour cream, pita bread and lime wedges.
