Cook the noodles: Boil according to package directions until just tender. Drain and rinse briefly under cool water to stop cooking and prevent sticking. Set aside.
Prep your veggies: Thinly slice or julienne your chosen vegetables.
Keep crunchy ones (like bell pepper and carrots) raw for contrast, or lightly steam broccoli and snap peas.
Make the sauce base: In a small bowl, whisk together peanut butter, soy sauce or tamari, rice vinegar or lime, maple syrup or brown sugar, chili sauce, and sesame oil. Add 1/3 cup water to loosen. Adjust with more water until it’s pourable but still creamy.
Sauté aromatics: Heat the neutral oil in a skillet over medium-low heat.
Add garlic and ginger. Cook 30–60 seconds until fragrant, stirring constantly so they don’t brown.
Combine sauce with aromatics: Pour the peanut sauce into the skillet with the garlic and ginger. Stir and let it gently warm for 1–2 minutes.
If it thickens too much, add a splash of water.
Add noodles: Toss in the cooked noodles and stir until evenly coated. If using tofu or edamame, fold them in now to warm through.
Finish with veggies: Off the heat, add the fresh veggies and toss to combine. Keep some for topping if you like a mix of textures.
Taste and tweak: Add more soy for salt, lime for brightness, chili for heat, or a pinch of sugar for balance.
Serve: Top with scallions, cilantro, sesame seeds, and crushed peanuts.
Squeeze over lime and serve warm or at room temp.
