2.Meanwhile, place chicken in medium saucepan of boiling water; return to the boil. Reduce heat; simmer, covered, about 10 minutes or until chicken is cooked through. Remove chicken from poaching liquid; cool 10 minutes. Discard poaching liquid (or keep for another use); shred chicken finely.
3.Preheat oven to 180°C. Oil shallow rectangular 3-litre (12-cup) ovenproof dish.
4.Heat oil in large frying pan; cook onion, stirring, until softened. Reserve half of the onion in small bowl.
5.Add garlic and cumin to remaining onion in pan; cook, stirring, until fragrant. Add chilli mixture, tomato paste, undrained tomatoes and oregano; bring to the boil. Reduce heat; simmer, uncovered, 1 minute. Remove sauce from heat. Season to taste.
6.Meanwhile, combine shredded chicken, reserved onion, half the sour cream and a third of the cheese in medium bowl.

8.Spread 1/2 cup tomato sauce into dish. Place enchiladas, seam-side down, in dish (they should fit snugly, without overcrowding). Pour remaining tomato sauce over enchiladas; sprinkle with remaining cheese.
