What exactly to eat for breakfast will really come down to your individual food preferences, but we can help give some ideas. We recommend combining a few healthy foods from different food groups to get a variety of nutrients that will start your day off well.
If you wanted to include your protein powder at breakfast time, that would be an excellent place for it! You could mix it in a smoothie with fruit, vegetables, milk (or milk alternative like soymilk), oats, peanut butter or powdered pb, etc. It makes a great shake for an on-the-go breakfast. Or you could just count the shake as your protein and eat some other foods separately, such as your Gainful + bowl of oatmeal.
You can also just go for all foods in the morning! If you aren't feeling a protein shake with breakfast, then good protein sources that are breakfast-friendly are eggs or egg whites (less calories/fat), turkey bacon or turkey sausage, soy milk, or oatmeal. And remember – nobody says you have to eat "breakfast foods" for breakfast.
Make sure to pair your breakfast with some whole fruit, veggies, and grains. A great example could be an egg white stir fry with vegetables, an apple, and a piece of whole wheat toast with some peanut butter. Include a glass of milk or soy milk and you have all the food groups!
