Heat canola oil in the pan over medium-high; add asparagus and cook, stirring, for 2 minutes. Add bell pepper, scallions, garlic and ginger; cook, stirring, until the vegetables are just tender, about 2 minutes. Add the cooked rice, soy sauce and vinegar to the pan; cook until the liquid is absorbed, 30 seconds to 1 minute. Fold in the cooked eggs. Remove from the heat; stir in sesame oil and hot sauce.
