What is that orange stuff on top??


can someone please tell me what that orange stuff on top is the part I have circled I recently got it this roll and it had it, I hated it I ended up taking it off and easting the roll with out it, It had a fatty bad taste.

edited: I’m like 95% sure it is not tuna or spicy tuna no way that is tuna it does look like it but I swear that was not tuna
