Shepard has never thought about issues Quarians had with their nutrition. So many problems just to satisfy their most basic needs. If Shepard had to the same thing every time she wanted to have a snack, it would soon drove her crazy. Once again, she felt pity for Zeto. 
"I am sure that Tali will give you some of her rations, if you ask her. And you don´t have to worry about ruining my tastes. My food will already take care of it. There are many good thing on Alliance military, but food surely isn´t one of them," Shepard sighed
It was true. Rock hard protein bars drowned in sauce that resembled oil in more than one way couldn´t be called gastronomical miracle by anyone who had better appetite than Vorcha. 
There even was a well known army legend about soldier fighting in Skyllian Blitz, who sharpened edges of his protein bar so much that he could gut Batarian with it.
"But it´s still a food I suppose..." she added after a while. "I will be going now. You can meet me at cantina table, fighting with my food..." and with that, she came out of cabin.

She went to her locker and picked out small box where she kept her ration packs. Shepard was a biotic so her rations were little bit bigger, but they tasted just as terribly as normal ones. 
She took one of them and prepared them on small tray, disgusted just by site of hated bars and sauce. After that she sat on a chair behind a small dining table. 
At first, she wanted to wait for Zeto before eating, but the hunger soon overwhelmed her.
