Not a big fan of Whole Foods Market, but I love their olive bar including all of delicacies that aren't olives. Here is a 24-hour room temp fermentation with wild starter that is moderately topped with:
Roasted red peppers
Sun-dried tomatoes
Capers
Anchovies
Mushrooms
Roasted garlic
While beans
Olives
Salami bits
Cippolini onions - balsamic glazed
Olive oil
