We are from the country of pasta! And, though we are not a family that eats pasta every day, I know MANY people that do it and at daycare they serve pasta every single day. So, I don't see any reason why you should not cook pasta every day. I agree with varying sauce, putting meat, fish and vegetable in it, and it becomes a quite complete meal. What I would do is giving her something else she likes less before it, to encourage her to vary her menu, doing it when she is hungry is better.
