Place the chicken breasts in a baking dish and set aside. In a large non-stick saucepan, heat the oil.
Add the green onions and garlic and saute over medium heat for 1 minute. Add the tomato puree, raisins, water and coriander and cook over low heat for about 10 minutes uncovered.
Pour the sauce over the chicken and bake for 30-45 minutes until chicken is cooked through.
