Chicken and Asparagus Stir Fry

So I went looking for a new asparagus stir fry recipe to try out on Friday while Jon works late and I found this one HERE. I'll let you know how it turns out.

Someone else's yummy recipe...click link above for actually author please.

About 1 lb boneless chicken breast, sliced thinly against grain
About 10 asparagus stalks, sliced on a bias, with the tough ends snapped off where it naturally breaks
About half an onion, sliced, or 1-2 scallions, sliced on a bias
1-2 tbspn rice cooking wine (optional)
2 cloves garlic, minced
Soy sauce
Corn starch
Oil
Salt and pepper

Marinate sliced chicken with about 1 tablespoon of soy sauce, 1 tablespoon corn starch, salt, and 1 clove of minced garlic for 20-30 minutes. Heat a wok or large pan with oil and stir fry until slightly browned. Add a tablespoon or so of rice wine if using while cooking. Remove from pan. Heat more oil and the rest of the garlic. Stir fry asparagus and onions until just tender, adding salt and a little pepper to taste. Return the chicken to pan. Taste for seasoning, adding more soy sauce if necessary. (If using scallion instead of onion I would add them here.) Mix about one tablespoon with 1/2 cup cold water with a splash of soy sauce, and optional teaspoon of sugar. Make sure your stir-fry is hot and slowly pour cornstarch mixture into the pan, stirring. Stir until the sauce is thickened and bubbly, and serve dish over steamed rice
