With only a slight adjustment of the fat portion in your meal you could add so much flavour, try this.

 60g of white wine vinegar, 20g Extra virgin olive oil, 20g of Tescos organic wholegrain mustard (black pepper to taste).

56kcals, 0.4g Protein, 0.7g Carbs, 5.4g Fat for a 25g serving which is plenty! 

NB: The reason I mention the Tescos mustard in particular is becauseits one of the very few mustards to not add extra crap!
