Slice sirloin steak into thin, narrow strips. In a medium bowl, combine salt, pepper and cornstarch. Add beef strips and toss to combine.
Heat oil in a wok or frying pan over medium high heat. Fry coated beef strips, in batches until crispy and golden brown. Transfer to a plate lined with paper towels. Set aside.
Pour off all but 1 tablespoon oil from pan. Lower heat to medium-low; add garlic and cook for a few seconds. Add bell pepper and stir-fry for another minute.
Add honey and soy sauce and stir to mix. Add the browned beef strips and stir to coat.
