Welcome from Oregon!! Congrats on finishing week 1, that can be a really rough one!
I like your menu, do you have any additional veggies in your salad or is it just romaine, broccoli and tuna with the vinegar and oil? My other wondering would be what you're doing exercise wise because it looks like it might be a little light on protein. (Then again, I'm really new and could very easily be very wrong).
