Caramelized Banana Steel-Cut Oats

In a medium pot, bring 4 cups water to a boil. Stir in oats and salt and cook 1 minute. Let cool, cover, and refrigerate overnight. In the morning, add milk and bring oatmeal to a simmer over medium-high. Cook until tender, about 10 minutes. Stir in vanilla. Transfer oatmeal to a 9-inch pie plate. Heat broiler, with rack 4 inches from heat. Top oatmeal with bananas and then raw sugar. Broil until bananas are caramelized, 3 to 4 minutes. Sprinkle with pecans, if using, to serve. It's also good with an extra splash or two of milk on it.
