Most of all, don't give in to the syringe feeding unless you really really have to, I know its tough. A couple of things you could try is seeing if Beanie will eat from a plate you're holding, or as suggested above putting food in her mouth but "whole" food, not blendered or mushed. Holding her while hand feeding veggies and lettuce might be a good mini-step, she might be hungry enough now she'll eat proper food that way.
I'm thinking maybe you will have to gradually work yourself out of the picture, Beanie is a stubborn girl! So maybe hand feed lettuce and veggies chopped/prepared how you'd feed normally, then maybe try off a plate that you're holding, then plate on the ground but you're there, etc. etc. Even rolling up greens and putting them in her mouth might be enough to trigger her to chew and swallow on her own. Eating the syringe mush from a plate you're holding might be a step or style to work in too.
Other than her eating, how's Beanie doing? Healing up nicely from surgery?
