Bone and skin the tuna. Slice the tuna into 4-ounce steaks. Pour the cracked pepper on a plate and press each steak on top of the pepper. Brush each with olive oil and place the steaks in the refrigerator until ready to cook.
In a hot saucepan quickly saute the steaks on each side for about 1 1/2 minutes per side. Don't overcook. Cut each tuna steak into ribbon slices.
In a pot of rolling boiling water, blanch the carrots and broccoli 30 seconds and then immediately plunge in an ice bath to cool. Drain and set aside.
In a large saute pan over high heat, add the oil, garlic, ginger, and soy sauce and saute, tossing 2 minutes. Add the chili flakes, bell pepper, mushrooms, spinach, blanched veggies, zucchini and scallions. Cook tossing for 3 minutes. Add a splash more soy sauce, if desired, and cook tossing 1 minute. Off the heat, evenly divide the slices of ahi and arrange artfully 8 ounces of stir-fried veggies per plate. Garnish with a sprig of cilantro, if desired.
