1 Preheat oven to 300°F. 2 Whisk ¼ cup cornstarch, flour, salt and pepper in a shallow dish. Pat tofu with a paper towel to remove excess moisture. 

3 Heat 2 tablespoons oil in a large nonstick skillet over medium-high heat. Dredge 4 tofu slices in the flour mixture, add them to the pan and cook until crispy and golden, about 3 minutes per side. Place the tofu on a baking sheet and transfer to the oven to keep warm. Repeat with another tablespoon oil.  4 Add the remaining 1 tablespoon oil, shallots and thyme to the pan. Reduce heat to medium and cook, stirring constantly, until the shallots are slightly soft and beginning to brown, 1 to 2 minutes. Add mushrooms and cook, stirring often, until tender and lightly browned, 3 to 5 minutes. Stir in Marsala. 5 Whisk the remaining 2 teaspoons cornstarch with broth and tomato paste in a small bowl. Stir into the mushroom mixture, return to a simmer and cook, stirring constantly, until thick and glossy, about 4 minutes. To serve, spoon the hot sauce over the tofu.
