Creating Mongolian Meatballs & Broccoli is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Prepare Meatball Mixture: In a large bowl, combine ground beef, breadcrumbs, green onions, soy sauce, minced garlic, grated ginger, egg, salt, and pepper. Mix until well combined.
3. Form Meatballs: Shape the mixture into meatballs, about 1 inch in diameter, and place them on the prepared baking sheet.
4. Bake Meatballs: Bake in the preheated oven for 15 minutes or until cooked through and browned.
5. Cook Broccoli: While the meatballs are baking, heat sesame oil and vegetable oil in a large skillet over medium-high heat. Add broccoli florets and stir-fry for about 5 minutes until tender-crisp.
6. Prepare Sauce: In a small saucepan, combine brown sugar, soy sauce, and any leftover juices from the meatballs. Heat until the sugar dissolves, creating a sweet sauce.
7. Combine: Once the meatballs are done, add them to the skillet with the broccoli. Pour the sauce over the mixture and stir to coat everything evenly.
8. Serve: Cook for an additional 2-3 minutes until everything is heated through.
9. Garnish: Optionally, sprinkle sesame seeds on top before serving.
