Dust chicken breasts with flour. In a large nonstick frying pan sprayed with cooking spray, heat oil over medium-high heat; in batches, cook chicken until browned on all sides, about 5 minutes per batch. Transfer to a 13 x 9-inch baking dish.
In a bowl, stir together salsa, honey, orange juice concentrate, soy sauce, cornstarch, mustard, garlic, and ginger; pour over chicken.
Bake, uncovered, in centre of oven for 20 to 30 minutes, or until chicken is cooked through. Garnish with parsley.
