Add the water and salt to a pot on the stove. Bring the water to a boil, then reduce the heat to a simmer (just below a boil) and add the oats.
1 cup water, ⅛ tsp salt, ½ cup rolled oats (also called old fashioned oats)
Cook the oats for 10 to 20 minutes, stirring occasionally, until the oatmeal is your desired consistency.
While the oatmeal is still cooking, mix the apples, brown sugar, cinnamon, lemon juice, and salt in a bowl and set aside for about 10 minutes while the oats finish cooking. While the fruit mixture rests, it will give off more liquid which will act as a fruity, lemony syrup for the oats.
1 apple, 1 to 2 tbsp brown sugar, ½ tsp cinnamon, squeeze of lemon juice, pinch salt
Serve the oatmeal with an optional splash of milk (dairy or non-dairy) and the apple cinnamon topping.
