Heat the avocado oil in a large wok or skillet over medium-high heat. Add the beef in a single layer (if possible) and stir beef until browned, 3 to 4 minutes.

Move the beef to the side of the wok and add the vegetables. Cook and stir vegetables for 2 minutes before stirring the beef into the vegetables to incorporate.

Pour ¼ to ⅓ cup of the stir fry sauce into the wok with the beef and vegetables and cook, stirring constantly, until sauce has thickened and created a sticky coat over everything, about 3 minutes. Taste stir fry and if desired, add more sauce.

Serve stir fry as is in bowls or with choice of steamed rice, quinoa, or vegetable noodles.
