Thanks for the ideas. I think I have figured out the menu and it will be:
Chips and dip (Crab and smoked gouda dip with artichoke leaves as the chips)
Hamburgers (Wagyu beef and andouille sausage with pecans, pickled okra, watercress and blue cheese with spicy mayo)
Potato salad (Grilled sweet potatos with poblanos and green onions in a honey vinaigerette)
Coleslaw (Spicy pineapple leek ginger slaw)
S'mores (homemade graham crackers and homemade marshmallows with dark chocolate and chopped almonds)
