Oh my, there's a lot we love at Trader Joe's. They have Cuban Black Beans in a can that work great as a side dish as well as in tortillas. They have delicious 12-grain and gorgonzola crackers. The New Zealand organic cheddar is great. All of their organic, fair-trade coffees are terrific. The veggies are tasty and of good quality. Their tofu is cheaper than any of the options at Whole Foods. TJ's has great vegetarian chicken strips that work well in fajitas. That's just off the top of my head....
peanut butter filled chocolate covered pretzels
nuts about raspberries and chocolate trail mix
everything pretzel thins
good selection and price of cheeses, wine, and beer in my opinion
instant steel cut oats
very cheap water crackers with a multigrain and flaxseed flavor
mochi ice cream
i like alot of their indian and thai marinades and stir fry sauces
microwaveable bowls of brown rice, they come in individual serving sizes which are great for work!
