I few ideas...and the Joy of Baking website (m)
The Joy of Baking website has some fun brunch recipes. If I saw those smoothie/frappes at an event, I'd head straight for those. Yum.
I also really like the Lemon Ginger Scones from the Joy of Baking website. I prefer them the same day they're made, but if you're testing recipes, see how you like them the following day. Here's a link:

and I'll post the recipe below.
I've been to a bunch of those kinds of events. I enjoy it when they serve mini muffins...so I can try several different offerings. It also cuts down on waste because people often grab a couple full sized muffins and only eat half.
I might think about doing a couple different composed butters...lemon ginger, berry, and something herby.
What about a bacon with brown sugar lightly sprinkled over the top...maybe with some herbs (rosemary)or pepper?
I can't wait to hear what you end up serving!
And here's my favorite scone recipe:
Lemon Ginger Scones
From the Joyofbaking.com
2 cups (280 grams) all purpose flour
1/4 cup (50 grams) granulated white sugar
1 teaspoon baking powder
1/4 teaspoon baking soda
1/4 teaspoon salt
1/2 cup (113 grams) (1 stick) unsalted butter, cold and cut into pieces
1/2 cup (70 grams) crystallized ginger, chopped into small pieces
Zest of 2 lemons
2/3 cup (160 ml) buttermilk
Egg mixture for brushing tops of scones:
1 large egg, lightly beaten
1 tablespoon milk
Turbinado sugar, or white granulated sugar, for sprinkling the tops of the scones.
Preheat oven to 400 degrees F (200 degrees C) and place rack in middle of oven. Line a cookie sheet with parchment paper.
In a large bowl, whisk together the flour, sugar, baking powder, baking soda and salt. Cut the butter into small pieces and blend into the flour mixture with a pastry blender or two knives. The mixture should look like coarse crumbs. Stir in the chopped crystallized ginger and lemon zest. Add the buttermilk to the flour mixture and stir just until the dough comes together. Do not overmix the dough.
Transfer to a lightly floured surface and knead dough gently four or five times and then pat the dough into a circle that is about 7 inches (18 cm) round and about 11/2 inches (3.75 cm) thick. Cut this circle in half, then cut each half into 3 pie-shaped wedges (triangles). Place the scones on the baking sheet. Make an egg wash of one well-beaten egg mixed with 1 tablespoon milk and brush the tops of the scones with this mixture. Sprinkle with raw sugar (if desired).
Bake for about 20 to 25 minutes or until golden brown and a toothpick inserted in the middle comes out clean. Transfer to a wire rack to cool.
Makes 6 scones.
