In a small mixing bowl, whisk together the soy sauce, honey, rice vinegar, toasted sesame oil, and red pepper flakes to create the glaze.
In a separate small bowl, combine the mayonnaise, Sriracha, and lime juice. Whisk until smooth and refrigerate the dip until serving.
Pat the beef cubes dry with paper towels to ensure a proper sear.
Heat the vegetable oil in a large heavy-bottomed skillet or wok over high heat until it begins to shimmer.
Add the beef cubes in a single layer, working in batches if necessary to avoid crowding the pan.
Sear the beef for 2 minutes without moving to develop a dark crust, then flip and sear for an additional 1-2 minutes.
Reduce the heat to medium-high. Add the minced garlic and grated ginger, sautéing for 30 seconds until fragrant.
Pour the soy-honey mixture into the skillet and toss the beef constantly for 1-2 minutes until the liquid reduces into a thick, sticky glaze.
Transfer the beef to a serving platter and garnish with sliced green onions and sesame seeds.
Serve immediately with the chilled creamy chili dip on the side.
