This spicy Szechuan tofu is easy to make and loaded with flavor. Pair it up with rice for a scrumptious vegan dinner that's better than takeout!
Stir the sauce ingredients together in a small bowl or container. Set aside.
Coat the bottom of the wok (or nonstick skillet) with half of the oil and place it over medium heat.
Once the oil is hot, add the tofu cubes in an even layer (Note 3). Cook the tofu cubes for about 10 minutes, flipping the pieces once or twice until they're browned and crispy on multiple sides. Transfer the tofu to a plate when done.
Add the remaining oil to the wok and raise the heat to medium-high.
Give the wok a minute to heat up, then add the bell pepper. Stir-fry the pepper just until it begins to deepen in color, about 1 minute.
Add the white parts of the scallions and Szechuan peppercorns to the wok. Continue to stir-fry the mixture for about 1 minute more, until the bell pepper becomes tender-crisp.
Return the tofu to the wok and carefully pour the sauce over the tofu. Continue stir-frying the mixture until the sauce thickens and coats the tofu and bell pepper, about 1 minute.
Remove the wok from heat.
Top the stir-fry with sesame seeds and the green parts of your scallions. Serve with rice.
