That dude has a good point they are actually all basically the same meal, just a sandwich with shredded chicken and essentially the same fillings. The original dude should have said chicken salad, chicken + leak pies, shredded chicken and sweet corn soup, etc.

The whole point is they were talking about mixing things up so the meals don't get boring, and if I serve you shredded chicken burritos one night, fajitas the next and wraps after that you'll go "Thanks but man... we just had the same dinner 3 nights in a row, could we have something else tomorrow please?"

PS A fajita is normally to be eaten with fingers, and rolled up. It could be eaten with a knife and fork but that would be similar to eating a slice of pizza with a knife and fork. Some people do it, just not the norm.
