I work at an infant school now and it is norma for their only to be one new lot of fruit or veg every day,although sometimes there are left overs from the day before as well.
There are always going to be options some children don't like whether it is banana, apple, prange, carrot or tomato.
I would just ensure DD had a piece of fruit in her bag just in case - and tell her to eat that instead. If the teacher says it is ok then there is no need for fuss.
FWIW my DD would happily eat tomatoes like this, but would hate banana - so you can't please evryone every day.
