What do you normally eat? I'd offer what you eat with some element or two included that will be something she is likely to eat, mixed with other things that aren't favourites or that are new. For example, mine will always eat wraps, cheese, sour cream and veg, so we can do lots of fajita options with different fillings (which we all eat), but even if they aren't keen on the chicken or the sauteed veg, I know they'll eat parts of the rest of it. Same with baked fish, homemade oven chips and peas. They like chips and peas, will generally try whatever protein I serve it with, but may not love it, so at least they'll eat the rest.
Quiche with salad is easy - store bought quiche then lots of salad bits, cucumbers, tomatoes, peppers, beetroot. Lots of different kinds of pasta - I do a creamy pasta with veg of any sort - cook pasta, chop garlic and sautee, add double cream, salt/pepper, add veg (mushrooms, tomatoes, peas, etc.)
Mine also really love a lentil stew with mushrooms and kale and crusty bread. Sounds weird but they inhale it.
Also anything (chickpeas, chicken, etc.) in pitas with hummus, plain yogurt, olives, tomatoes, cucumbers, etc. to make sort of little kebabs is good. Again if they don't love the chickpeas, there is still plenty of filling stuff to put in the pita.
