If you had a list already prepared, and that list was communicated to the sub who then ignored it, then I'd say the sub overstepped. If there's any possibility that she didn't get that list or didn't realize it was from you, then she probably came up with a "traditional" party list of sugar this and sugar that. I'd say that's more a throwback to years past and not a personal slight. She did you a favor stepping in on short notice, something people often don't appreciate in a sub. She hasn't been involved for a year, and maybe she either misses it or really wanted to "earn her keep" by using her expertise, however antiquated you find it.
What I wouldn't do it spend a ton of time being upset. I'd either email a list to the parents and say that you'd like to offer options including cheese, crackers, fruit, whatever. Ask if even half the people would switch from what they signed up for and go for something new. You also can't be sure that some of the parents didn't "help" with the new list, wanting more treats and less healthy stuff. So be gentle to that they don't get the same feeling that you got in the sense of the preferred list being ignored. Nobody likes getting pushed around even if it's not intended. You don't like it - they might not either.
Instead of having people manually sign up on a list, have you considered something like SignUp Genius? A lot of classrooms and clubs around us use that. The coordinator (in this case, you), makes a list of things needed: cheese, crackers, veggies/hummus, etc. You can list them individually, or by category. When I do our neighborhood block party, I do Appetizer 1, 2, 3, 4, 5, 6 and then side dish 1, 2, 3, 4, 5, 6, then desserts, then equipment/supplies (paper goods, tables, utensils, etc.). People who sign up can list what they’re bringing within that category. You can put a heading on it with the date/time of the party, number of servings, and so on, and the website then will send members a reminder of what they signed up for (at whatever frequency you set up). If someone changes what they are bringing, you get notified – you’ll always have an up-to-date list, and you get a notice whenever there’s a change or a new sign-up. It’s a lot easier, you can do it from home (ahead of the club or even when you are sick), and it gets to people who miss the club one week. And you don’t have to chase people to remind them of what they agreed to. It would help a lot of the administration and it would have helped you avoid the problem you encountered with the sub.
