Preheat the oven to 250 degrees F.
In a medium bowl, mix the potato pearls with the butter, parsley, and salt and pepper, to taste. Set aside.
Preheat a flat-top griddle or medium skillet over medium-high heat. Season the mahi fillet with the herb butter, salt, and pepper. Top the fillet with the potato pearl mixture. Place the fish on the hot griddle, with the potato pearl side down. Sear on each side until golden brown. Place the fillet in a non-reactive pie pan, and then add 3 tablespoons lime broth, 2 tablespoons water, and the white wine. Place the pan in the oven, and bake for 8 minutes. Remove fish to a large serving bowl with the roasted garlic and remaining lime broth. Top with the fried spinach, and garnish with the lemon and parsley sprig.
