2 small or 1 medium Shallot, finely chopped
2 tablespoons white wine vinegar
1 cup Olive Oil
S and P to taste
Combine chopped shallots, vinegar, oil, juice of one orange salt and pepper in a jar, close tightly and shake vigorously.
Using a mandolin set to quite a thin setting, slice fennel and apple.
Combine everything, mix, let sit for a few minutes, (but not so long that it wilts!!) and eat.
