I'll focus on the main SoulRes cast for this:

Grey: I feel like she'd like a lot of dairy-based stuff—coffee ice cream in particular. Not much of a cook and often eats cheap.
Emily: Big on anything meaty, typically red meat. Also loves energy drinks and sodas. Doesn't cook due to circumstances but would like to learn.
Jia: Warm but not spicy foods—enjoys breakfast meals like hotcakes, eggs... big coffee drinker. She can cook but it's rare, a morning woman she is not.
Chris: She’s somewhat pescatarian, preferring the finned stuff to the shellfish. She can cook on occasion but loves her wife's cooking.
Amber: She loves that wet stuff, soup and its ilk in particular (gumbo especially). She's THE chef.
Vera: They live for pasta dishes. They cook but don't often get the chance to.
Sophia: Prefers lighter yet balanced fare. Salads that cover a wide variety of food groups are her preference. Detests pizza in part due to her old job with Pizza Peeps. Disastrous at food prep.
