I’ll second M2C, meal time feeding may help force her to eat if it isn’t available at all times.

Switching foods may help keep things interesting, more expensive to buy many small bags, yes, but could be effective. If you don’t want to go straight canned, maybe a dehydrated food? Honest Kitchen, Sojos, etc… may be a good fit for her. And if you really want her to graze, you could feed that at meal times, slightly less than you should, and keep the kibble for grazing.
