Fass fud is all she knows, as previously mentioned she probably barely ate anything resembling a home cooked meal* as a child since her parents were too strung out most of the time to know if it was New York Or New Year never mind feed a child something vaguely nutritious. Similarly with seesneen literally everything she eats with garlic salt/powder/black pepper/onion powder/tapatio- it's safe. (And the fact that she probably couldn't name another spice or herb, but that's by the by.)
That's why she gets all "nervous" when she's trying something new; it's not that she's fussy, but the thought of not liking something and therefore not getting the dopamine hit from her drug of choice terrifies her. We've all seen how she reacts when she doesn't like something- the toddler tantrum she threw over the sandwich she made with the "TASTES LIKE LIDURUHL POISON" buffalo chicken is a classic example. Most people would just either choke it down as to not waste food or just make something else, but not our gorl. She's every bit the junkie her parents were.
*except Gramma's Respeeee if that even qualifies as food
