You definately cant have nan bread as a healthy extra im afraid you can only have wholewheat bread!
A normal plain naan is 21.5 Syns or peshwari would be 23.5
A 360g serving of korma is 16.5 Syns
Youd be better off either making it yourself or going for a rogan josh with plain rice no naan which is around 7 syns for a 360g portion
