In a small mixing bowl, whisk together soy sauce, 1/4 cup water, honey, rice vinegar, sesame oil, ginger, and garlic to create the teriyaki base.
Heat a large skillet over medium-high heat. Add the ground beef and cook until browned, breaking it into crumbles with a spatula. Drain any excess rendered fat.
Pour the sauce mixture over the beef and bring to a gentle simmer.
In a small ramekin, mix the cornstarch and 1 tablespoon of cold water to form a slurry. Stir the slurry into the skillet.
Simmer the beef for 2 minutes or until the sauce thickens into a glossy glaze.
Assemble the bowls by dividing the cooked jasmine rice and steamed broccoli into four containers.
Top each portion with the teriyaki beef mixture.
Garnish with sesame seeds and sliced green onions before sealing for meal prep.
