Make the Basil Oil: Bring a pot of salted water to a boil. Dip Basil and scallions in to make more pliable and make the color more vibrant. Cool under cold water or ice. Strain as much water as possible out.
Chop the basil and scallion. Place in blender with garlic, oil, salt, and pepper. Blend on high speed until the mixture is a vibrant green. You could strain out the herbs after for a clean look.

Wilt the spinach: heat olive oil in a large saute pan. Toss in the spinach. Sprinkle in salt and pepper, and begin stirring the spinach. It will begin to wilt. When all the spinach is wet and wilty, remove from heat and strain out extra liquid.

Heat the stuffed portobellos about 8 to 10 minutes until hot. Reheat the sunchokes. When all items are hot, Plate the meal: make a base of the sunchoke puree. Balance the portobello on top or put it to the side. Prop the carrots against the mushroom. Then drizzle basil oil and balsamic over and around the plate. Serve immediately.
