Prepare your mise en place.
In a small bowl, whisk together the tamari, 2 tablespoons (30 ml / 1 fl oz) of water, rice wine, and cornstarch to create the sauce.
Set aside.
Prep the asparagus. Snap off the tough, woody ends. If the stalks are thick, you can peel the bottom half.
Slice the asparagus on a diagonal into 2-inch pieces.
Heat a wok or large skillet over high heat.
Add the peanut oil.
Once shimmering, carefully add the patted-dry tofu cubes.
Stir-fry for 5-8 minutes, until golden and crisp on all sides.
Transfer the tofu to a plate and set aside.
In the same wok, reduce the heat to medium-high.
Add the minced ginger and stir-fry for about 30 seconds until fragrant.
Add the prepared asparagus and toss to coat.
Add 1 tablespoon (15 ml / 0.5 fl oz) of water, cover, and steam for 2 minutes until the asparagus is crisp-tender.
Uncover the wok and add the red bell pepper and sliced water chestnuts.
Continue to stir-fry for another 3 minutes, until the peppers are slightly softened but still have a bite.
Return the golden tofu to the wok. Give the sauce mixture a quick re-stir (the cornstarch settles!) and pour it into the pan.
Toss everything together and cook for 1 minute, until the sauce thickens and coats all the .
Remove from the heat.
Drizzle with the sesame oil and a few drops of hot chili oil.
Toss one last time and serve immediately over a bed of fluffy brown rice.
Stir-frying happens fast! Have all your vegetables chopped, tofu cubed, and sauce mixed before you even turn on the heat. This 'mise en place' is the key to a stress-free stir-fry.
