Step 1: Cook the Potstickers to Golden Perfection - Start by cooking your potstickers according to the package instructions. Some will have you boil them and some will suggest pan frying. I like to pan fry mine because you get those lightly crispy bottoms that add a lot of texture. Once they are cooked through, set them aside on a plate. Try not to snack on too many at this stage. I know it is tempting.
Step 2: Sauté the Onion for a Flavorful Base - Grab a large skillet and place it over medium high heat. Add the vegetable oil and let it warm up for a moment. Toss in the sliced onion and give it a stir. Let it cook for about three minutes, stirring occasionally. You want the onion to soften and start to turn slightly translucent. This step builds that first layer of flavor that everything else will sit on.
Step 3: Add the Vegetables and Build Texture - Now add the bell peppers, carrot, broccoli, and snap peas. Stir everything together so the vegetables are evenly coated in the oil. Let them cook for about five minutes, stirring as you go. You are looking for that sweet spot where the vegetables are tender but still have a bit of crunch. That contrast is what makes this dish so satisfying.
Step 4: Create the Savory Sauce - Once the vegetables are just about where you want them, add in the minced garlic, sesame oil, rice vinegar, and soy sauce. Stir everything together and let it cook for about one minute. You will start to smell that rich garlicky aroma almost immediately. This is where the magic happens and everything starts to come together.
Step 5: Add the Potstickers and Bring It All Together - Gently add the cooked potstickers back into the skillet. This is the moment to be a little careful. Use a soft hand when stirring so you do not break them apart. Toss everything together and let it cook for another three to five minutes until the potstickers are warmed through and coated in the sauce.
Step 6: Finish with Toppings and Serve - Turn off the heat and sprinkle sesame seeds and chopped scallions over the top if you like. These are optional but they really do add a nice finishing touch. Serve everything up while it is warm and enjoy that moment when everyone digs in.
