Please help me brainstorm ideas for a birthday party lunch menu, theme is tea party so finger foods would be fun! DD will be 4 years old, attendees will be 5-6 other children, similar age and ~12 adults.

Party is at 11am, we've historically had a full lunch and it's all the same attendees, so I'd like to stick to that. I'm in a rural area so no access to take out of any sort, but I do have Costco!

Looking for 90% prep ahead food. Veggie and fruit trays are the only thing on my list so far!
