In reply to matnoo: Was shown this the other day, its mega!
Cut an avocado in half, take the stone out and fill the gap with a 50/50 mix of balsamic vinegar and olive oil(it will separate naturally, don't try to mix it!) When you eat, just get an edge of the oil and vinegar and enjoy!
Easy starter, vegetarian and tasty!
For a main I'd go for pasta with sauce, add tofu or quorn if she eats it, nice and simple and light, goes with the avocado.
For pudding get two portions of vanilla ice cream and two slices of extra gooey chocolate cake, mash together and serve!!!!!!!! Easily indulgent and can be focused onto any favourites of your chick, (strawberry cake, etc...)
