1 medium head of fennel
1 apple
1/2 medium celery root
Squeeze of lemon juice
1 garlic clove
1/4 cup plain non-fat yogurt
1 tablespoon buttermilk
1 tablespoon apple cider vinegar
1 teaspoon lemon juice
1/2 teaspoon Dijon mustard
Salt and pepper to taste
2 tablespoon pine nuts pumpkin seeds, OR hazelnuts
1 bunch watercress
Using a tabletop, small mandolin, slice the fennel, celery root and apple into very thin slices (thinnest setting – it’s important that they be thin since it's a raw salad).
Place in a medium bowl, sprinkle on a little lemon juice to keep from turning brown, and toss. Set aside.
Make the dressing. Mince the clove of garlic as finely as possible, almost to a paste. Place in a small bowl.
Add the yogurt, buttermilk, vinegar, lemon juice, and mustard, and whisk together.
Add salt and pepper to taste.
Add dressing to the fennel / celery root / apple mixture and toss.
Refrigerate for at least 2 hours, and ideally overnight to allow the flavors to seep into the vegetables.
Just before serving, add the watercress and toss again.
Top with pine nuts, pumpkin seeds or hazelnuts.
