Step 1

Brown the ground beef in a large skillet over medium-high heat with 1/2 tablespoon of olive oil. Break apart, fully cook, and push to one side of the pan.

Step 2

Add the remaining olive oil and zucchini. Cook until the zucchini starts to pick up color and soften, about 3 minutes.

Step 3

Add the mushrooms and stir everything together before adding the Teriyaki sauce. Cook until the sauce is evenly distributed and sticking to the stir fry, about 1-2 minutes.

Step 4

Serve the ground beef over rice with the sauce. Garnish with scallions and sesame seeds, if desired.
