FCO-DEL: 2 meals & DEL-TPE: 1 meal
If it's around lunch time for Delhi departure then it's lunch.
AKL-BNE: 1 meal & BNE-TPE: 2 meals

Real Biscuits, Sandwiches, Rice Noodles.
Obviously crackers, cookies, nuts and biscuits and others are also available.
I don't think skipping meals is a good idea, though.

I am unsure about it since your flight departs at Roma, so the food is prepared at Roma. I wouldn't say the European choice is worse in this case. Same for Delhi and flights departing from Auckland and Brisbane.
For flights departing from Taipei, the Asian type should be better but not always the case.
