I need a delicious biscuit, bun or other bread recipe that is nut free and dairy free to go with butternut squash soup for my strictly kosher fam?

Hi! :)

I made a tutorial recently to make homemade bread (you can eat it with sweet food as well as any kind of meal):

I hope it can help you! :)

How about:

Oatmeal cherry schmalz cookies from Michael Ruhlman (wild, but will play off the apples & sweetness of squash)

James Beard refrigerator potato bread (original calls for butter as the fat but I've made it a zillion times with olive oil and great results)

Not a roll or bun, but how about focaccia, cut into squares? No dairy/nuts, easy to do and great with soup. With butternut squash and apple soup, I'd sprinkle the dough with fresh thyme or rosemary, along with the salt and olive oil. Many recipes online - this one is particularly good: https://food52.com/recipes/28786-saltie-s-focaccia
