Geez, just remembered Calorie King website so I looked up souvlaki on that. It said 2090 kilojoules, or for those that work in calories 498 calories.
This would mean its approx. a third of my daily kilojoule intake, so I reckon its definitely worth a try as an occasional treat. We have to be realistic with our meals after all - I haven't had takeaway since new year
I might look up that tazeki sauce (not spelt right), that would be the closest to the sauce and minus that, should work out better that way. Garlic sauce is especially yummy but with the marinated beef it should be flavoursome and I guess if its not I could always use my trust chilli sauce!
Thanks for the help guys.
