Try just leaving finger food by her, she maybe better grazing that eating normal meals.
My (now late) mother rarely ate a 'proper' meal but consumed quite a lot this way.
Obviously be careful what you pick to leave, but most foods will quite happily sit on a plate by a person for some hours before they become unfit to eat.
Make a sandwich with a soft filling with just one slice of bread, cut the crust off and cut into 6 mouth sized pieces.
a few cheese cubes?
Some soft fruit, just ready to pop in
KitKat fingers always went first!!
You will soon see if she eats anything/what she chooses, left to her own devices
