In a small glass jar add the chopped shallot, minced garlic, red wine vinegar, olive oil, sea salt, and freshly cracked pepper, to taste; whisk well, and set aside to let the flavors mingle.
Place in a large pot of boiling water for 3-4 minutes, I like mine tender but still crisp.
Drain and place in ice-cold water to stop them cooking and to preserve the bright green. Drain and place in a bowl.
Add the sliced onion, fresh dill, and salad dressing to taste. Toss until evenly coated.
Place in a serving dish and sprinkle the top with feta cheese. Serve and enjoy.
