Instructions

Toast the walnuts in a dry skillet over medium heat, stirring frequently, until fragrant and slightly darkened, 3–4 minutes. Transfer to a plate to cool.
Make the vinaigrette: In a small bowl, whisk together apple cider vinegar, whole-grain mustard, Dijon, honey, minced shallot, thyme, salt, and pepper. Slowly whisk in olive oil until emulsified.
Toss the apple slices with lemon juice to prevent browning.
In a large bowl, combine watercress and arugula. Drizzle with just enough vinaigrette to lightly coat and toss gently.
Divide greens among plates. Top with apple slices, shaved Irish cheddar, radishes, toasted walnuts, and chopped parsley.
Drizzle with a bit more vinaigrette and finish with a pinch of salt and pepper to taste. Serve immediately.
