Our neighbor's husband passed away last weekend, after a long battle with cancer. We aren't super close to them, but our street is pretty close-knit in general & friendly, so of course I'd like to reach out. I'm wondering how to offer condolences, without being invasive.

Should I drop off food (in freezer ready containers)? Leave a card? If I leave food, do I just assume no one has food allergies? Maybe a basket of snacks? I'm at a loss ...

Another neighbor (who I'm very close to) mentioned that the family (they have 4 young sons) is pretty private, and would like this time respected, which means no visitors. I do know that the husband was a jazz musician since the 70's, so us neighbors will be making a contribution to a youth jazz program in his honor.
