Allergy Friendly Chicken McArabia

"McArabia is McDonald's grilled chicken sandwich made with pita bread. It is available in different countries under different names, for example Pakistan, Singapore, Greece etc. The first time I made the copycat recipe, it was a total hit. At the time I just used the recipe as is, so my kids did not eat it because of all the allergens it contained. This time around I decided to make it allergy friendly. McArabia patty is made with chicken mince, spices, egg and a bread slice. Then for sauce it uses mayonnaise and vinegar and the patty is than sandwiched between a pita bread. Here are the substitutions I made for the Allergy Friendly McArabia, to make it gluten free, vinegar free and egg free."
