Step 1

Place the oats, apple pieces, raisins, milk, cinnamon, salt and, if using, nuts in a small container or Mason jar. Stir together to combine. Editor's Tip: Mixing everything together like this will let the ingredients soften overnight. If you prefer crunchier apples and nuts, don't mix those ingredients with the rest; instead, layer them on top inside the jar to keep them crisp and crunchy when you serve.

Step 2

Seal the container and refrigerate overnight. Then, simply open and enjoy. Editor's Tip: If you prefer chunkier, less-milky oats, simply drain the milk before serving. It's all about how you like it!
