Glad to hear that she's settling in so well, Jennifer.

Trout is certainly a good, safe, cheap, readily available option, and it can be cut into suitable sized pieces and frozen. Once she's accepting trout pieces it will be easier to convince her to accept other food items, such as frozen/thawed pink mice. Trout is a very strong smelling fish, so the scent transfers well onto other things (especially fingers!)
Welcome back, after your short involuntary absence!!!!
