I read the article, as well. Nice job!
TJ's is a nice place to shop, if available. But, for many zoners, there are not enough TJ's close enough in proximity to make shopping there a viable option. I am about 1.5 hours away from one myself, and have only been there once.
I think that the objective for any zoner is to find solutions for what works in their area. Maybe some are fortunate to have a TJ's right around the corner, but if not, I know that more and more grocery stores are catering to the needs of the people. Our local market carries veggie blends that go well in soups without much prep. They have a good variety of meat, and the labels are more clear than ever regarding the fat content. They have a fresh produce count that changes every day, and pride themselves on the huge variety available (and this is a fairly small town). Excellent frozen section, can always get my frozen berries in large economical bags. Always good options available for salsa, wide variety. They also sell a wide variety of hummus brands. Believe it or not, not all hummus is created equal! LOL! One of the newest features is that they recently developed a salad bar right in the store. So, all I have to do is load up on pre-cut veggies from the salad bar, and suddenly there is no work at all involved in prepping a quick veggie platter or putting together a salad. Hmmm, one time I was shopping and was due for a snack, so I just filled up a plate of cut red pepper strips and grabbed some pre-cooked chicken right off of the salad bar. I believe they even had some almond slivers right there for salad toppings, so I tossed a few onto my plate. Voila! Instant snack!
Even if your grocery store does not have some of these modern features (there is one store that is closer to me, in my hometown), it is really just a matter of knowing what is available at that particular store, and learning how to work it into the lifestyle.
