I just typed ww pro points greggs tuna crunch into google and im getting 14PP on brown bread from various sites. Don't know for 100% if thats exact though
Wow 15! Bless him, he tried lol
I did try to look on greggs for any values but I didn't find it the simplest to navigate! I always use the search on this site because I find a lot of other sites unreliable thank you
