Whisk together egg, oil, and milk until smooth. Sift together flour, baking soda, and salt; add to egg mixture along with brown sugar, and oatmeal; stir until just combined.
Heat a lightly oiled griddle or frying pan over medium high heat. Pour or spoon the batter onto the griddle, using approximately 1/4 cup for each pancake. Brown on both sides and serve hot.
