Thank you all for your wonderful suggestions and ideas.
We sat down with our nanny a few days ago.
She said she was overwhelmed with DD being picky with her food before becoming vegetarian. For example, DD would refuse multiple choices of food offered by the nanny while making school lunches. Dinner leftovers (involving meat), turkey sandwiches and occasional hotdogs were something that my DD would actually eat. It's a nut free school, so now DD's lunches would be more challenging with no meat and my DD being picky.
She said she was supportive of my DD becoming a vegetarian, but wanted her to take some responsibility for planning her meals - meaning DD should do some research about nutrition and come up with different choices to substitute the meat part of the meals. Not cook her own meals, although she would be expected to help on no homework days.
It's been a few days and things seem to be going well. We got veggie bacon and burgers in the freezer. Eggs, lentil soup, some indian food and a few other options.
It will probably take a few more days to adjust, but so far so good.
Thank you everyone
