FOR THE POTATOES
Steam potatoes over high heat until just tender when pricked with a sharp knife. Set aside to cool. When cool, peel (the peelings should slide right off), and cut into small, ¼ -1/2 inch cubes. Drizzle with just a little olive oil to keep moist. Season with salt and pepper to taste. Refrigerate until ready to use.
FOR THE PICKLED RED ONIONS
Place onion slices in a colander in the sink. Pour boiling water over the top to soften.
Rinse with cold water, then place in a glass or other non-reactive bowl.
Combine water and rice vinegar. Pour rice wine vinegar and cold water over the top (this should cover the onion slices).
Gently stir in salt and pink peppercorns.
Cover and refrigerate at least one hour before serving.
When ready to serve, cut into 1-inch slices or whatever size you like best.
FOR THE VINAIGRETTE
In a small bowl, combine the garlic, lemon zest, lemon juice, and Dijon Mustard.
Slowly whisk in the extra virgin olive oil, and keep whisking until emulsified.
Salt and pepper to taste.
TO ASSEMBLE:
Place potatoes on an oval platter.
Sprinkle green onion, feta cheese, pickled onions, olives, and fresh oregano over potatoes.
Drizzle dressing over all. Top with edible flowers. Serve immediately.
