Clean and trim the root ends of the enoki mushrooms, then gently pull them apart into small bundles.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the shrimp to the pan in a single layer and sear for 2 minutes per side until pink and opaque.
Remove the shrimp from the pan and set aside on a plate.
In the same pan, add the minced garlic, grated ginger, and red pepper flakes, sautéing for 30 seconds until fragrant.
Toss in the enoki mushrooms and baby bok choy, stir-frying for 2 to 3 minutes until the mushrooms begin to soften and the greens wilt.
Return the shrimp to the pan and pour in the tamari and toasted sesame oil.
Toss everything together for 1 minute to coat thoroughly in the savory sauce.
Garnish with sliced green onions and serve immediately while hot and aromatic.
