Mix honey, 1/2 cup canola oil, and salt together in the skillet; return to heat. Gently pour water into honey mixture and stir; cook until mixture is bubbling, 2 to 3 minutes. Stir oats mixture into honey mixture and cook, stirring frequently, until heated through, about 5 minutes. Remove skillet from heat.
Preheat oven to 350 degrees F (175 degrees C).
