In a small saucepan, bring the balsamic vinegar and shallots to a rolling boil over high heat. Lower the heat to medium, and continue cooking until the liquid is syrupy and reduced by half, about 15 minutes.
While the balsamic reduction is cooking, place a wire rack 6 inches from the heating element in the oven, and turn on the broiler. Coat a parchment lined baking sheet with the melted ghee, and arrange the eggplant slices on top. Season liberally with salt and pepper, and flip the eggplant slices over to season the other side.
Broil the eggplant rounds for 2 to 3 minutes. Using tongs, flip each slice over, rotate the tray, and broil for another 2 to 3 minutes or until golden brown. Set aside to cool.
In a bowl, combine the Macadamia Nut “Ricotta,” basil, and olive oil. Season with salt and pepper to taste, and then stir to thoroughly incorporate.
Assemble the stacks by spreading generous spoonfuls of the herbed “ricotta” and drizzles of balsamic reduction between layers of eggplant and tomato slices.
Garnish with basil and a final splash of balsamic reduction before serving.
