Saucy Steak 'n' Onions

In nonstick skillet, heat 1 tsp (5 mL) oil over medium-high heat; cook steak, turning once, for 6 minutes for rare, or until desired doneness. Transfer to cutting board; tent with foil. Let stand for 10 minutes.

Meanwhile, in clean skillet over medium heat, combine onions and red pepper; cook, stirring often, for about 5 minutes or until softened. Dissolve cornstarch in 2 tbsp (25 mL) of the stock. Add remaining stock to skillet and bring to boil. Whisk in cornstarch mixture and stir until thickened, about 3 minutes. Sprinkle with pinch each salt and pepper. Slice steak into thin strips and serve with sauce.
