Greggs is really crap for veggies, so I’m really not sure. The cheese and onion pasty is horrible, with that snotty processed cheese. The veg pasty that some Greggs do is OK but still has that snotty texture to its insides. To be honest all of the pasties they do are a bit shit.
Do they still do that Tuna Crunch baguette that has loads of red onion in it? I’d probably get that.
