Fermented bean loaf would be something akin to tempeh: https://en.wikipedia.org/wiki/Tempeh

Not bad in a curry, if you can get the traditional style with whole and not lightly ground beans.

While “tofu” is well enough known in Western culture that I could have used that word, I had her say “fermented bean loaf” since “tempeh” isn’t.

I’m also sure that some variation of Seiten [https://en.wikipedia.org/wiki/Wheat_gluten_(food)] might also be part of their diet.

"Stop crying, and, get dressed. My love belongs to Seidr, wholeheartedly. I can't simply give it to you. And I will be faithful to her. But I have decided to help you against Loki."
Still pressing herself against Hans, Gná looked up into his eyes. Hans wondered if she was actually batting her eyes at him.
"Oh thank you so, Madison. But tell me, do you not find me at all attractive? Look at me and tell me you feel nothing stirring inside you."
Hans thought briefly that she would be feeling something stirring outside him pretty soon. Especially with her breasts pressed against his chest that way. His left hand, seemingly of its own accord, started to trace its way down her spine.
Hans shook his head to dislodge those thoughts. And moved his hands to her shoulders, holding her in position as he took a small step back.
"You're very beautiful, Gná. And I would be lying if I said I felt nothing. I may be young, even among humans, but I still know the difference between desire and love. I hope you find love someday. I truly do. But I can't offer it to you."
Still wiping tears, Gná set her head back against his chest, "You do not deserve the ill use I have put you to. I shall see to it that you do not regret helping us." She sniffed, then drew back. "Oh my."
"Is something wrong?"
Gná placed her hand to her nose. "Lord Madison, I hope this does not offend you, but you smell of that, charred meat, you were eating this morning."
"I'm sorry. I didn't realize. I guess I could use a shower."
Gná dressed, while Hans tried not to watch, assisted by her two handmaidens. Twins, with long black hair, like Gná, but not quite as pretty. The only real difference between them being that one wore a red dress with a blue bodice, and the other wore the same colors reversed.
Gná smiled. "Would a bath do, Lord Madison?"
"If it's not too much trouble."
He got an odd look from the twins. That must have been a pretty good social faux-pas.
Gná turned to each of them in turn, "Tiek, Please take Lord Madison to the bathhouse. Kiet, see to it we have a feast for tonight. Set out extra eggs and cheese for him. Not all humans are fond of bean curd or fermented bean loaf."
The one with the blue bodice stepped up to Hans. Tiek, he guessed. In the most adorable, little-girl voice she addressed him, "This way, My Lord."
"H. . . Er, just 'Madison' will be fine."
Gná watched Tiek titter and lead him away. She motioned Za, her Captain of the Guard, and sister, to approach her. She would need her help in this matter.
Za commented, "You place much faith in a boy, My Lady. Can he really best Loki and rejuvenate our race?"
Gná smiled at her sister. "I intend to see to Loki's disposition myself in the end. But we need him to first remove Hel and Jormungand from our way. Should he fail, Seidr's child may serve that purpose just as well when he reaches manhood, perhaps better should he inherit his mother's powers as well."
She feigned inspiration. "See to it that the bathhouse is well used and that none demure in his presence."
"My Lady?" Poor Za looked confused.
