Review summary

Updated on Feb 2026
  • Flavour: The Red Leicester cheese overpowered other ingredients, making the dish too salty for some; consider using cheddar or mozzarella instead.
  • Ease of prep: The portion size was too large for a typical lunch; consider preparing only half the recipe.
  • Suggestions: For a milder flavour, try omitting the wholegrain mustard or using less Red Leicester cheese.
