I was introduced to this easy, versatile, and overall good-for-you recipe several years ago when working as a health educator and have made numerous times since then. Most recently, I had a few apples that needed used up and ended up making a triple-batch. You can use essentially any type of fresh (peaches, apples, berries, etc.) or dried fruit (cranberries, raisins, etc). that you enjoy.
1 1/2 c quick-cooking oats
3/4 to 1 c diced fresh fruit (or dried, according to your tastes)
2 c milk
1/4 c sugar
3/4 tsp vanilla extract
1/8 tsp salt
optional: cinnamon and/or nutmeg, sprinkled to taste; syrup drizzled over the oatmeal after baking, if desired
1. Pre-heat oven to 350F. Spray a 9x13 baking dish with cooking spray. Combine the oats and fruit in the baking dish.
2. In a bowl, combine the milk, egg, sugar, vanilla, and salt; stir until the sugar is dissolved.
3. Pour the liquid mixture over the oats and fruit.
4. Bake for 30-35 minutes, or until the center is set.
Notes: this can be made in a muffin pan to yield individual-sized portions (will not take quite as long to bake) and you can prep this the night before and cover and refrigerate until baking the next morning. I find that this dish re-heats well in the microwave, making it great for busy mornings.
