Sheet Pan Beef and Broccoli

Add the sirloin, broccoli, and onion to a Ziploc gallon bag.
In a small bowl, add the soy sauce, garlic, honey, sesame oil, rice vinegar, ginger, salt, and pepper and whisk until combined.
Add the marinade mixture to the gallon bag, seal it, and massage until everything is covered in the marinade. Let the bag sit for 15 minutes.
Preheat the oven to 425°F, spray a sheet pan with nonstick spray, and set aside.
Spread the meat and broccoli mixture over the sheet pan and bake for 15-20 minutes.
While the sheet pan is baking, make the sauce.
Add the soy sauce, garlic, honey, sesame oil, rice vinegar, ginger, salt, and pepper in a saucepan and whisk until combined.
On high heat, let the mixture come to a boil.
Add the cornstarch to the water and whisk until dissolved.
Reduce the heat to medium-low and whisk in the cornstarch mixture until the mixture thickens.
Remove from the heat and set aside.
Pull the sheet pan out of the oven and drizzle the sauce over the top.
Garnish with sesame seeds and green onion if desired.
Serve and enjoy!
