Preheat an oven to 375F. Mix together the olive oil and miso paste until smooth. Brush mixture evenly over sliced baguette, crack pepper over the top and arrange in a single layer on a rimmed baking sheet. Bake for 8-10 mins or until crisp and golden. Allow to cool slightly before serving.
While the crostini bake, Arrange burrata on a platter surrounded with sliced nectarines and roasted peppers. In a small bowl, combine 2 T olive oil, honey, olives, oregano, & mint, and add Sel Magique to taste. Drizzle over burrata + nectarines/roasted peppers and serve with crostini. Enjoy!
