In MI the Costcos irregularly stock Ling Ling potstickers, which are a huge downfall for me when I want to do a cheap and easy dinner. I end up stocking up with bags of those damned things.
I've bought their potstickers and stashed them in the freezer. I can't justify it nowadays, too high a % of fat, I scan the ingredients lists. If something is over 30% fat, especially over 50% I usually can't justify putting it in my cart. I prefer to keep that % under 15%.
TBH, I still have some of the sauce that came with their potstickers in my fridge! It's a kind of sweet soy, probably with ginger, sealed in plastic bags. I should either toss it or use it.
