Serious Eats says Trader Joe's potstickers are "the only one we'd stock in our home freezers" of the store brands they tried, and The Daily Meal says they're No. 1 among TJ's appetizers. To fancy things up a bit, try TJ's recipe for potsticker soup -- you'll need some chicken broth, baby spinach, soy sauce, and a mirepoix, among other ingredients.
Reminds me: I really need to make another trip there. I don't even know what a mirepoix is!
