Why not let her outside after you eat? If she sees you eating, she will start to become hungry herself. Then let her outside when you are done. By that time she will really want some food. Then, motive her to come back inside with her dinner. She can associate the house with yummy food.

As for the barking, you can get one of those citrus-spray collars for that. I believe you can get a kind where you press a remote when she barks and it sprays her. The regular kind sometimes goes off when the dog doesn't even bark.

Find something that motivates her like nothing else.

Maybe you can resort to only letting her outside if she is onleash? That way you could have control of her. If she pulls, I'd suggest a training tool liek a prong collar, a halti, or a whistle collar.
