Savory Beef and Onion Stir-Fry

In a medium bowl, combine the thinly sliced flank steak, baking soda, and cornstarch. Mix until well-coated and let marinate for at least 15 minutes.

Heat a large skillet or wok over high heat and add 1 tablespoon vegetable oil. Once hot, add the marinated beef and stir-fry for 3-4 minutes, until browned and about 75% cooked. Transfer the partially cooked beef to a plate and set aside.

Add another 1 tablespoon of vegetable oil to the skillet or wok, and add the peeled pearl onions and sliced bell pepper. Cook for 2-3 minutes, until onions are caramelized and bell pepper is slightly softened.

Return the cooked beef back to the skillet or wok, and add the store-bought stir-fry sauce. Cook for an additional 2-3 minutes, stirring frequently, until the beef is fully cooked, and the sauce is thickened.

Serve the beef and onion stir-fry with steamed jasmine rice for a satisfying meal.
