Snacks and refreshments for neighborhood Hasidic Jews?

We live in a neighborhood where every week we have a procession of Hasidic Jews passing right in front of our house. We’ve had the thought that it would be nice, especially on hot or cold days, to set up out front with some snacks or drinks for those who are interested.

However, we know very little about the Hasidic tradition and although we think we have a grasp on their dietary restrictions just from looking online, we wanted to check in with somebody about what good refreshments would be.

Edit:

Thank you for all your thoughtful replies! I had no idea a gesture like this would have so much connotation and so many possible interpretations (and am very glad I asked before I just set something out and risked offending anybody in my neighborhood!). I used to have a Jewish professor who often said (with a funny kind of pride) “for every two Jews, three opinions.” I can practically hear him laughing at how easily I stepped into such an immediate example of that principle.

I think we’ll hold off, but if summer gets real bad this year we may consider some bottled water.

Thanks again!
