There isn't a TJ's convenient to me, but when i worked near one, about 7-8 years ago, there are some things i still remember loving:

1. $3 chuck- i was only 21-23 when i had that job- money was tight post-college!
I would still buy it now, as cooking wine, or wine to make a lowcarb sangria.

2. frozen salmon and frozen mahi burgers- sooo convenient. you just bake them.
toppings: mahi with fresh salsa and sour cream
salmon with wasabi aioli and goat cheese
either with aioli and maybe sf relish

3. these little snack packs of celery with pb to dunk (the pb is not totally sf, but the portion control made the trade off worth it to me).

of course, i loved all the cheese, produce, etc.....the above 3 things just still stand out in my memory (which is impressive 7 years later, so they must have been good!).
