Make the vinaigrette:Whisk together the avocado oil, tamari, Thai sweet chili sauce, fish sauce, lime juice and zest, garlic, ginger, honey, and sesame seeds. Add sliced jalapeño if you like extra heat.
Let the flavors meld (optional but recommended):If time allows, refrigerate the vinaigrette for about an hour to deepen the flavor.
Season the steak:In a small bowl, combine the kosher salt, black pepper, granulated garlic, granulated onion, and Chinese five spice. Pat the steak dry and season evenly on all sides.
Sear the steak:Heat a cast iron skillet over high heat and add a drizzle of avocado oil. Sear the steak for a few minutes per side, cooking to your preferred doneness.
Rest and slice:Transfer the steak to a cutting board and let it rest for at least 10 minutes. Slice thinly against the grain for maximum tenderness.
Assemble the salad:Arrange the greens, cucumber, tomatoes, red onion, and avocado on a large platter or bowl.
Finish and serve:Top with the sliced steak, drizzle generously with vinaigrette, and garnish with fresh mint, cilantro, and crushed peanuts. Serve immediately.
Notes
Limes: Some limes are juicier that others. Add the zest and juice of 1 lime to begin. Taste, and if you think it needs more, lime juice, add more.
