I'm going to add to this post, as interestingly I've just bought some wholemeal pittas from the co-op (2 packs for 80p!). I've checked the ingredients and they have no oil in...
Ingredients:
Wholemeal wheat flour, water, salt, yeast, preservative (calcium propionate).
Nutrition:
Cals 130(220per 100g)
Protien 6.2 (10.4 per 100g)
Carbs 24.7 (41.2 per 100g)
Fat 0.8 (1.3 per 100g)
Fibre 3.7 (6.2 per 100g)
Sodium 0.2 (0.3 per 100g).
Now I don't know about you but these look very similar to the Asda ones listed above... Although there is 0.1g fat and 4 more calories more there is 0.8g more fibre in the co-op ones. Do you think I should email SW and suggest it as a HEXB??
