Put the mashed potatoes in a bowl.
Add the crabmeat, julienned basil, and salt, and pepper to taste.
Stir potato mixture thoroughly to combine.
Spread the potato mixture on one side of each ono fillet to form a crust.
Heat the oil in a heavy nonstick saute pan or skillet over medium heat.
Add the ono, crust side down, and saute for 3 mins. until the crust turns golden brown.
Turn the fillet over and saute for 2 mins. longer, or until opaque throughout.
Heat a separate dry, heavy saute pan or skillet over medium heat for 2 mins.
Add the bacon and saute for 4-5 mins. until crisp.
Remove and mince the bacon; set aside.
Drain off all but 1 T. of the bacon fat and increase the heat to medium-high.
Add the shallot and garlic to the bacon fat.
Immediately add the spinach and cook until it begins to wilt.
Transfer spinach mixture to a colander and press with the back of a wooden spoon to release excess moisture.
Chop the spinach mixture and set aside.
Pour the cream into a sauce pan and bring to a boil.
Cook to reduce the cream by about two-thirds or until thickened and paste-like.
Add the spinach to the cream and cook for about 1 min.
Season with salt and pepper to taste.
Set aside and keep warm.
In the center of warmed serving plates, arrange the blanched carrots and top with creamed spinach.
Place the crusted ono on top of the spinach.
Garnish the ono with the bacon and basil.
