Best food for elderly grandmother who is not eating?

Even though a curry (even a mild one -- indian or thai) might open her appetite, it may also upset her stomach as in, give her gas. I'd try cooking or baking safe stuff. During my gradma's last days, my mum prepared several small containers of things she liked, like breaded fish or breaded cauliflower/cheese or even a chicken burger, a little bit of rice or pasta, some salad and then dessert (cakes or fruity yogurt). She ate what she could. If I knew how to cook back then, I'd probably have a turkey & leek pie and meat or fish hot-pot.
