Steam the potstickers or dumplings according to the package instructions until they are heated through and tender. Once done, transfer them to a large bowl and add a teaspoon of sesame oil to prevent sticking; alternatively, you can use a splash of water instead of oil.
In a small bowl, combine Tamari, balsamic vinegar, and maple syrup to create your dressing. Pour this mixture over the steamed dumplings in the bowl, being careful not to break them apart as you toss them gently to ensure they are well-coated.
Cut the heirloom tomatoes into wedges and thinly slice the cucumber and scallions. Add these fresh vegetables along with the optional red chili pepper into the bowl with the dumplings and toss everything together until evenly mixed.
Tear basil leaves over the top of your salad just before serving to maintain their bright flavor and aroma. Finally, sprinkle toasted sesame seeds or crispy fried onions on top for added crunch and garnish.
This Potsticker Salad (Dumpling Salad) can be served immediately at room temperature or chilled slightly in the refrigerator if preferred. For an added kick, provide garlic chili sauce on the side for those who enjoy extra heat.
