COOK THE OATMEAL: Bring 2 cups water to a boil. Add the oats and salt and reduce to a simmer. Simmer, stirring occasionally, until the liquid has been absorbed and the oats are tender, 10-15 minutes. Remove from heat.
PREPARE THE TOPPING: Divide the cooked oats between two bowls. Top with the sliced bananas. Sprinkle the brown sugar over both bowls in an even layer to coat the bananas and oats.
BRULEE: Fire up your torch (see equipment notes) and sweep it across the surface of the oatmeal, moving it back and forth at a steady pace until all of the sugar has caramelized.
