Honestly my quick breakfast is a smoothie. I have a juicer and a big jar, and on weekends I’ll fill the jar with fresh juice: carrots, apples, ginger, lemon. Then during the week I throw a banana, some frozen strawberries, some whey protein and Amzing Grass (powder super greens) sometimes some cashews with my fresh juice and it’s the best dang smoothie you ever had!
An apple, and some natural juice are good options for when one is in a hurry. Keep in mind breakfast is the most important meal of the day so is better to take a time and have a good breakfast to star your day motivated 🙂
