Meanwhile core and de-seed the red peppers and chop into small pieces.
Cut the chicken in small cubes.
Add chicken + bell peppers + garlic to the steamer on top of the potatoes and steam for additional 9 min.
Let cool slightly and then puree in food processor (or blender) until smooth and creamy, adding water from steamer if needed.
