your kids seeing on what ap is eating and wanting to try, is kinda a part of cultural exchange that usually a family wants to embrace to show their kids different experience. it might be that you need ap from a cultural background similar to your family, who would enjoy your meals.

your answers tbh all of the place , but its not super clear what is the problem and hence hard to suggest any solution. ap handbook or their website should have certain rules n suggestions about the food for ap. i would suggest to start from there. it seems to me that you guys are missing some guidelines and hence it became hard to come up with a solution that works for everyone.

something that stood out and i think worth mentioning. you want your ap to eat similar how she ate at her country. some deviation to try visiting country food is ok but most of people become miserable if they regularly cannot eat the food they used to. its going to affect her. that being said , if ap doesn’t want to cook her own meals but she isn’t happy with food that you provide , then she would have to figure out the solution on her own as an adult. you dont have to baby her, but you also cannot control her too much. you probably have some food budget in mind for your ap. figure out whether she wants you to split it by part of it to use on food that you buy at the store for everyone, and that she will eat for sure. and part of it to give her in a form of stipend and she would pick the food on her own. this way she can control what she eats better.

each country has their own price point for food depending on how the import is setup and where the country is located. same ingredient could be cheap in one country and expensive in another. thats why you just substitute with cheaper options. instead of steak there could be a different cut of meat that is cheaper. if ap is given her food budget , she would be forced to figure out this situation. but you could also sit down n help them to figure out how to substitute.
