Creating Beef & Onion Stir-Fry is a straightforward process if you follow these steps:

1. Prep the Ingredients: Slice the beef against the grain into thin strips. Slice the onions and bell pepper (if using) into thin pieces. Mince the garlic and ginger.
2. Mix the Sauce: In a bowl, combine the soy sauce, cornstarch, honey or brown sugar, and beef broth. Mix well until smooth.
3. Heat the Oil: In a large skillet or wok, heat the vegetable oil over medium-high heat until hot.
4. Cook the Beef: Add the sliced beef to the skillet. Stir-fry for 3-4 minutes or until browned. Remove from the skillet and set aside on a plate.
5. Sauté Onions and Vegetables: In the same skillet, add the sliced onions and bell pepper. Stir-fry for 2-3 minutes until softened.
6. Add Garlic and Ginger: Stir in the minced garlic and ginger. Cook for an additional 1-2 minutes until fragrant.
7. Combine Everything: Return the cooked beef to the skillet. Pour the prepared sauce over the beef and vegetables. Stir well to coat everything evenly.
8. Thicken the Sauce: Continue cooking for 2-3 minutes, stirring occasionally, until the sauce thickens and bubbles.
9. Season: Adjust the flavor with salt and pepper to taste.
10. Remove from Heat: Once the beef is heated through and the sauce is thickened, remove from heat.
