I was going to suggest salmon, but not necessarily canned. Do you have access to a microwave?

Also in my WW universe 3 egg whites are a better choice than 1 whole egg. That might be one way to achieve more protein and less fat. Hardboiled is convenient.

And finally, if you were actually a wobbling pudgebucket, which you're not, then what would that make me? Your wobbling pudgebucket turquoise-wearing bookend?
