Ingredient Alternatives

Beef
Provides savory protein and stir-fry texture.

Alternatives: Flank steak, Sirloin, Pre-cut stir-fry beef. Slice across the grain as thinly as possible. Partially freezing the beef for 15 minutes makes slicing easier.
Bell pepper
Adds sweetness, color, and crunch.

Alternatives: Red pepper, Yellow pepper, Capsicum. Cut peppers into similar widths so they cook evenly.
Oyster sauce
Adds body and savory sweetness.

Alternatives: Hoisin plus soy sauce, Vegetarian oyster sauce, Soy sauce plus a pinch of sugar. Taste before adding more salt because oyster sauce and soy sauce both season strongly.

Cook Better Next Time

Return vegetables only at the end so they stay crisp-tender.
