Dad here looking for salty snack musts

Shortly after us breaking up we found out she was expecting. It was semi planned, but sorely so on my end as I was having inner issues as far as trauma with my own dad. Fast forward a month and we're trying to figure stuff out and hopefully go on a couple dates after the new year.

Anyway, she's staying with mom and she's been super sick to the point of going to the ER to get her nausea under control. What are good snacks to tame it to where it's bearable? She did cheese and crackers at first then wasabi nuts. Looking to experiment even if it means having to toss out stuff that doesn't work. Shooting in the dark here.
