Hi there! I'm a little bit aware of Tali's situation, and the first option is more than doable. Most of the kitchens play to exceptions, if she expects to find food that she can eat, she will find it. It would be perfectly suited to her nutritional needs.

She would be allowed to have her environmental suit, and we would make special adjustments for her safety if we ever had an event in which that was taken away/discuss it with you.
