In a small mixing bowl, combine soy sauce, oyster sauce, honey, ginger, garlic, cornstarch, and chicken broth; whisk until smooth.
Heat vegetable oil in a wok or large heavy-bottomed skillet over high heat until it reaches its smoke point.
Add chicken strips in batches to avoid crowding; sear until browned and internal temperature reaches 165F (74C), then remove from pan.
Add asparagus and red pepper flakes to the remaining oil in the pan; stir-fry for 3 minutes until tender-crisp.
Return the chicken to the pan and pour the prepared sauce over the mixture.
Toss continuously for 60-90 seconds until the sauce has thickened and glazed the ingredients.
Remove from heat, finish with sesame oil, and serve immediately.
