In a medium bowl, whisk together the honey, soy sauce, sesame oil, minced garlic, grated ginger, and black pepper until well combined.
Add the steak cubes to the marinade and toss until all pieces are coated. Cover and let marinate in the refrigerator for at least 30 minutes, or up to 2 hours for deeper flavor.
In a small bowl, mix the cornstarch with water to create a slurry and set aside.
Heat a large skillet or wok over medium-high heat. Remove the steak from the marinade (reserving the marinade) and add the steak cubes to the skillet. Cook for about 3-4 minutes, stirring frequently, until they are browned and cooked to your desired level of doneness.
Once the steak bites are cooked, pour the reserved marinade over the skillet, bringing it to a simmer.
Stir in the cornstarch slurry and let the sauce thicken, stirring constantly for about 1-2 minutes until it becomes glossy and sticky.
Remove the skillet from heat and let it cool slightly before plating.
Garnish your sweet and sticky steak bites with sliced green onions and sesame seeds before serving.
