She could have anything made with potatoes, carrots, beans, rice, etc etc. Those dietary limits are easily worked around by anyone with an IQ above single digits. Also, beans and rice combined give a complete amino acid profile and is a staple of poor people around the world. And 90% of black Africans are lactose intolerant, so the use of a black woman in the picture is ironic.
From my experience, even when you do work around a menagerie of actual restrictions (allergies and intolerances) combined with choices (vegan, low carb, ect.) They will turn around and complain about the lack of options, as if YOU were the one that imposed it on them.
Also, restaurants do preo work to allow them to prepare meals more quickly (cooking at a restaurant is far different than preparing a meal at home). That means a specialty meal has to have the prep work done from scratch, to acomadate changes in the recipie and ensure against cross contamination. This means a specialty item could easily take over an hour to prepare. Also, if a restaurant doesn't have any menu items with specific unprocessed ingredients in them, they won't have those ingredients on hand.
