Making the Big Mac in a bowl later (the recipe off here) and really looking forward to it

Other half is very skeptical and not keen on trying it lol. Is there anything I can do to his to make it extra tasty? He's not on a diet and is convinced he's going to be served a plate of 'diet food' lol (even though he's been quite happy with all meals so far!)
Thanks in advance
