Slice the flank steak into ¼-inch-thick strips against the grain.
Place the sliced steak and cornstarch in a zip-top bag. Seal and shake until the beef is evenly coated.
In a small bowl, whisk together the sesame oil, soy sauce, brown sugar, water, rice vinegar, and cornstarch. Set aside.
Heat the avocado oil in a large skillet over medium-high heat.
Add the beef in a single layer, cooking in batches if needed. Cook undisturbed for 3–4 minutes per side, until browned and cooked through. Remove from the skillet.
Add the garlic and ginger to the skillet. Cook for 30–60 seconds, until fragrant.
Pour in the sauce and cook for 2–3 minutes, stirring, until the sugar dissolves and the sauce thickens.
Return the beef to the skillet and toss until evenly coated in the sauce.
Serve warm, topped with sesame seeds if desired.
