I would like to get ideas for more easy to prepare breakfasts especially for busy mornings

Boil and peel a bunch of eggs, and invest in trail mix (or ingredients for it) that you can portion into bags to take with you. Every morning, you can take an egg or two and a bag of trail mix and eat it on the way. Don't forget your water bottle, you need to stay hydrated during the day too!

Overnight oats.
Banana pancakes (made the night before. Just microwave them).
Smoothie with a bit of oats.
Avocado toast with poached egg.
Rice cakes with peanut butter and blueberries.
