For the tahini sauce in step 1:
For the tofu seasoning in step 2:
For step 3:
To garnish:
In a food processor, add the tahini, soy sauce and ginger. Zest the lemon and reserve separately for Step 4. Squeeze one lemon (or 2 tbsp lemon juice) into the tahini mixture. Blend with cold water until saucy (about 4 tablespoons). Set aside in a bowl in fridge.
In a shallow dish or large plate, stir together the cornstarch, sesame seeds, 4 teaspoons black pepper, and a big pinch of salt. Cut the tofu lengthwise into ½-inch-slices, then crosswise in half. (You’ll have about 16 pieces.) Pat the tofu dry, then add to the cornstarch mixture and press and turn to coat the tops and bottoms.
In a large, nonstick skillet, heat 1 teaspoon oil over medium-high. Add the snap peas and cook, stirring occasionally, until blistered and just tender, about 3 minutes. Season with salt and transfer to serving plates.
Reduce heat to medium and add the remaining 2 tablespoons oil. Add the tofu and cook until golden-crisp on both sides, 4 to 6 minutes per side. Turn off the heat, sprinkle the tofu with the reserved lemon zest and shake the skillet so the zest adheres to the tofu.
