"Everything is spelled out," says city official Silvana Sari. "There's no room for manoeuvre for the supplier."
All food is organic except for meat and fish products, up from an organic portion of only 10 percent in 2001, she noted.
The cost per meal has gone up around 50 euro cents (75 US), to five euros, of which parents pay two euros.
"It was easier to convince the children than the parents and teachers," Sari said, adding: "But now everyone is imitating us, both in Italy and abroad."
French Agriculture Minister Michel Barnier, a recent visitor to the school, wants to have fruit distributed free to French schools.
"It was difficult to get the children to eat fruit and vegetables, but now that they are used to it they all eat (at least) a little," said Angela Di Nicola, the school principal.
Sari's rules forbidding second helpings of pasta may spur a better liking for vegetables, while more and more parents have stopped giving their children snacks such as slices of pizza to eat during play periods.
The children seem to understand the benefits of organic food.
"It's good for us," said seven-year-old Federico, while Sonia chimed in: "It helps you grow."
The children are given carrot slices and cherry tomatoes when they go on field trips.
One popular holdover from the old regime is ice cream -- although it is allowed only twice a week.
The reasoning is sound: its organic equivalent is much higher in calories.
"They eat what we give them," Di Nicola said.
