Apples: Add sliced apple, sugar, almond butter, cinnamon, lemon juice, and salt to a saucepan. Cook on the stove over medium heat for 8 to 10 minutes, or until apples have softened some.
Assemble: Spoon oats into two bowls or jars. Evenly top with apple mixture, milk, and raisins (you do not need to stir). Cover with a lid or plastic wrap and set in the refrigerator 6 hours (or overnight). Serve cold or heated in the microwave.
