For the dressing, combine the parsley, vinegar, lemon juice, mustard, olive oil, garlic, honey in a blender or immersion blender. Salt and pepper to taste the dressing and set aside in the fridge.
Next, coat all the ahi in fine ground black pepper and fry in a skillet on medium high heat in the peanut oil. Using tongs, flip the tuna once, cooking for about 5-8 minutes total for medium rare. Set the tuna aside to cool.
On one or two large platters arrange all the vegetable in groups. Get all of the greens washed and into a seperate bowl. Slice the tuna carefully across the grain and arrange it on top of the vegetables.
Serve with crusty baguettes and the salad dressing on the side. Voila!
