Season the sirloin steak with sea salt and black pepper on both sides.
Heat olive oil in a stainless steel or cast iron skillet over medium-high heat until shimmering.
Sear the steak for 4 to 5 minutes per side until it reaches your preferred level of doneness.
Transfer the steak to a cutting board and allow it to rest for at least 5 minutes.
In a large mixing bowl, combine the shredded cabbage, kale, snap peas, and shelled edamame.
In a small jar or bowl, whisk together the tamari, toasted sesame oil, rice vinegar, grated ginger, and minced garlic.
Pour the dressing over the vegetable mixture and toss thoroughly to ensure everything is evenly coated.
Slice the rested steak against the grain into thin, tender strips.
Divide the dressed greens into a bowl, top with the sliced steak, and garnish with sliced almonds for extra crunch.
