We make new year’s resolutions in an attempt to start afresh and turn over a healthy new leaf. Losing weight is often on top on the list – but no need to survive on egg white and spinach alone! Shift to a fibre-rich diet with ample sources of lean protein – it’s the simplest way to reduce your calorie intake without eating less! Here’s a good way to start: this flavorful dish is high in proteins and fibers, contains some healthy fats and will fill you up so you can get on with your day.
