Which regionals? You say lots. At ASA, we get (as does Skywest from what I understand) little snack packs that we can pick up in the crew lounge only. They currently consist of a crunchy breadstick and a mini-box of raisins or something. They used to be pretty good (chicken salad tins, biscuits, etc) up until a few years ago, but I guess they didn't want to spend the cash on them anymore. Plus we were told that people were stealing them and taking them home.

My understanding is that Pinnacle used to get meals catered for their longer Mexico flights (ATL-MTY, DTW-MTY). When DL shifted that flying back to us, they were accidentally catering for us too until our MGMT found out about it. Now it's just the leftover First Class Meals.
