This is as simple as dishes get; just mix rolled oats, dried fruit, the seasonings of your choice, and milk and let sit over night before eating.
3/4 rolled oats
1/4 dried fruits
honey, sugar, maple syrup, and spices to taste (cinnamon and cardamom are both good options in the spice category)
2% to whole milk to cover.
Mix everything and let sit in the fridge for at least 6 hours to blend.
