Preheat your oven to 375°F and position the rack in the middle.
Heat olive oil in a 10-inch oven-safe skillet over medium heat, then add asparagus and bok choy, sautéing for 5-6 minutes until tender.
In a large bowl, whisk together eggs, almond milk, salt, pepper, and garlic powder until well combined.
Pour the egg mixture over the vegetables in the skillet, gently stirring to distribute evenly.
Cook on the stovetop for 3-4 minutes without stirring until edges begin to set.
Transfer the skillet to the oven and bake for 12-15 minutes until the center is set and the top is lightly golden.
Remove from oven, let cool for 5 minutes, then slice into wedges and serve.
