Whisk together the sauce by combining low sodium soy sauce, water, hoisin sauce, rice vinegar, honey, chili garlic sauce, sesame oil, grated garlic, and grated ginger in a small bowl.

Cook the beef in a large skillet over medium-high heat for about 5-7 minutes until fully browned, adding ground beef and sliced green onions.

Add pineapple into the skillet, sautéing it for 2 minutes until warm. Pour in the prepared sauce and heat until bubbling.

Thicken the sauce by stirring in the cornstarch slurry; cook for an additional 3-4 minutes until the sauce clings to the beef and pineapple.

Garnish with sliced green onions and sesame seeds before serving over rice or quinoa.
