Toss the 16 oz cubed meat with 1 tbsp cornstarch and 1 tbsp soy sauce in a medium bowl. Let sit for 5 minutes.
In a small bowl, whisk together the 1/2 cup creamy peanut spread, remaining 2 tbsp soy sauce, 1 tbsp rice vinegar, 1 tsp sesame oil, 1 tbsp honey, 2 cloves minced garlic, 1 tsp grated ginger, and 1/4 cup warm water until smooth.
Heat 1 tbsp vegetable oil in a large skillet or wok over medium-high heat. Add the marinated meat and cook for 5 to 7 minutes until browned and cooked through.
Pour the sauce mixture over the cooked meat in the skillet. Stir continuously for 2 to 3 minutes until the sauce thickens and coats the pieces evenly.
Remove from heat, garnish with 2 sliced green onions, and serve hot.
