Savory Beef Stir-Fry

Dissolve beef bouillon cube in boiling water in a large bowl.

Stir soy sauce, cornstarch, teriyaki sauce, and sugar into the water.

Lay beef strips into the soy sauce mixture; stir to coat beef entirely.

Heat oil in a large skillet over medium-high heat.

Cook and stir vegetables in hot oil briefly, about 1 minute.

Stir water chestnuts into the vegetable mixture, place a cover over the skillet, and cook at a simmer until the vegetables are hot, about 5 minutes.

Remove vegetable mixture with a slotted spoon to a large bowl, reserving juices in the skillet.

Pour beef with soy sauce marinade into the hot skillet; cook and stir until browned completely, about 5 minutes.

Return vegetable mixture to the skillet; bring to a simmer.

Cook and stir until completely hot, about 2 minutes.
