Chinese chicken and asparagus in brown sauce

We were intrigued by a chicken and asparagus stirfry recipe that didn’t feature white sauce: https://thewoksoflife.com/chicken-asparagus-stir-fry/ For the chicken breast, we used 1 1/4 medium boneless breast, sliced across the grain as thin as possible. We found this sauce delicious and satisfying. (Aug. 2022)
