You know, soy milk is a beverage that has protein.
Let me spell that out:
it is a beverage (can be pulled out of the fridge and consumed in a matter of seconds)
that has protein (can be used to substitute for part of a meal)
There have been days when I got my carbs from apple juice and my protein from soy milk. And also, like, a carrot or two. (Those can also be eaten with peanut butter.)
With all due respect, if you haven't tried peanut butter at least once with every form of easily-retrievable food found in a fridge (tortilla, rice, carrots, celery, apples), then you have been managing your executive dysfunction waaaaay too effectively. What kind of ADHD meds are you on?
Almost. I'm a backup you created of yourself. You don't remember why. Neither do I. One of us was going to write it down, but by the time the pencil was in hand, the thought was gone from both of our minds.
