This is a one tray wonder for busy evenings. Sweet potatoes, Brussels sprouts and grapes roast together until caramelised at the edges while the kielbasa turns crisp and golden. Brussels sprouts are part of the cruciferous family and higher intakes of these vegetables have been linked with better cardiovascular markers, while grapes bring polyphenols that may nudge systolic blood pressure down by a small amount. Easy to make and easy to love.
