I’m not sure if this is still the case, but they used to cater 16 plates of every option in Mint so that no one would ever not get their choice. Leftovers become crew meals.
Doing the math; 16 plates each of 5 options is 80 plates. 3 plates each for 16 passengers is 48 plates, leaving 32 plates for 4 flight attendants and 2 pilots (and whoever is jumpseating, they feed them too due to the surplus of food). They might say no, but if you’re still hungry, you can try asking for seconds.
