In a small jar combine all the vinaigrette ingredients. Shake the jar until emulsified or whisk ingredients in a bowl. Set aside.
In a large flat bottom bowl, add the arugula, almonds, cherries, farro, fennel, and mint. Lightly drizzle a few tablespoons of the vinaigrette over the salad and gently toss.
Plate the salad on 6 individual salad plates and top each with prosciutto and goat cheese crumbles. Add more vinaigrette as needed at the table.
