Place the dry soy chunks in a heat-proof bowl and cover with boiling water for 10 minutes until fully softened.
Drain the soy chunks in a colander and squeeze them firmly to remove as much excess water as possible.
Heat the avocado oil in a large skillet or wok over medium-high heat.
Add the rehydrated soy chunks to the skillet and sauté for 5-7 minutes until they develop a golden-brown, crispy exterior.
Add the sliced cremini mushrooms and sugar snap peas to the pan, cooking for 4 minutes until the mushrooms are tender and browned.
Stir in the minced garlic and grated fresh ginger, cooking for 60 seconds until aromatic.
In a small jar or bowl, whisk together the tamari, toasted sesame oil, and rice vinegar.
Pour the sauce over the stir-fry and toss everything together for 1-2 minutes until the glaze thickens and coats the ingredients.
Season the dish with sea salt and black pepper to taste.
Garnish with thinly sliced green onions and serve immediately.
