If you don't have time to cook, you may as well consider eating canned tuna - it is very easy and fast to get prepped - just open the can and you are ready to go. Also, it takes just 3 minutes to boil your eggs, and like 5 minutes to make your oalmeals. All of those meals will do much more for you in terms of energy and workout quality, and they are a much healthier option, so I would go with them.
