Bring the milk (or almond milk or water) to a boil in a large pot. Stir in the oats and salt, reduce heat to low, and simmer for about 5 minutes for rolled oats (or according to package instructions for other types), stirring occasionally until the oats are soft and have absorbed most of the liquid.
Divide the cooked oatmeal into bowls. Let everyone add their favorite toppings to create their own ultimate oatmeal bowl.
