Add the artichokes and cook, stirring occasionally, until lightly browned in spots, about 5 minutes. Add the white wine and cook until nearly evaporated. Add the spinach and cook, stirring, for 1 minute. Add the cream cheese, Parmigiano-Reggiano and lemon zest and season with Tabasco. Cook, stirring, until the dip is creamy, about 2 minutes. Transfer to a bowl and serve warm or at room temperature with the Spiced Pita Chips.
