Rub olive oil over the chicken and season with salt and pepper.
Cook the chicken by steaming it for about 20-25 minutes until tender.
Let the chicken cool, then chop it into 1/2-inch pieces.
In a bowl, mix mayonnaise, Greek yogurt, curry powder, mango chutney, and lemon juice.
Add chopped chicken into the creamy mixture and stir until thoroughly combined.
Sprinkle with slivered almonds before serving.
