Overnight oats variation: Combine 1/2 cup old-fashioned rolled oats with 1/2 cup water and a pinch of salt in a jar or bowl. Cover and refrigerate overnight. In the morning, add toppings. Eat cold or heat up. Makes about 1 cup. Steel-cut oats variation: Bring 1 cup water and a pinch of salt to a boil in a small saucepan. Add 1/3 cup steel-cut oats, reduce heat to a bare simmer, cover and cook, stirring occasionally, until most of the liquid is absorbed, 15 to 20 minutes. Remove from heat and let stand, covered, 2 to 3 minutes. Add toppings. Makes about 1 cup. People with celiac disease or gluten-sensitivity should use oats that are labeled “gluten-free,” as oats are often cross-contaminated with wheat and barley.
