Heat 1 tsp oil in a large non-stick frying pan over medium-high heat. Add the chicken pieces and cook, stirring occasionally, for 5 minutes, or until cooked through. Remove the cooked chicken into a large bowl.

Add another 1 tsp of oil into the frying pan and add onions and mushrooms. Cook, stirring occasionally, for 8 minutes, or until soft. Remove from the frying pan and put in a bowl with the chicken.

Heat another 1 tsp of oil in a frying pan and add the asparagus. Cook, stirring occasionally, for 5 minutes, or until tender, yet still crispy.

Add the chicken, mushrooms and onions back to the frying pan to the asparagus and mix. Add minced garlic, pepper and soy sauce and keep stirring, until everything is hot again.

Taste to see if the stir fry is salty enough. If more salt is needed, add more soy sauce until it tastes perfect.

Remove the chicken stir fry for heat and serve.
