If you are using frozen vegetables, use a steamer to cook and defrost the vegetables for about 15 minutes or until the vegetables are soft and cooked. Heat another 10 mL (2 tsp) of canola oil at medium heat and stir-fry the vegetables for 1 to 2 minutes. If you are using fresh vegetables, omit the steaming and stir-fry the vegetables for 4 to 5 minutes
