Peel and spiralize your vegetables - the noodles can get crazy long so I sometimes break them up as they are falling into the bowl but this is not necessary.
In a small bowl, whisk together the sesame dressing ingredients - you can add a splash of water if it seems too thick (this just depends on the kind of peanut butter you use).
Heat up a few tablespoons of toasted sesame oil in a large saute pan (or wok) and when you see a few whisps of smoke just starting to appear, add the sweet potatoes. Season with salt, cover and let cook 2-3 minutes.
Now add the zucchini, season with salt and toss everything together. Cover and cook another 2-3 minutes.
Remove the lid and start checking for doneness - you want the noodles to be tender but not mush.
Notes
You can absolutely use pasta or do a combo of veggies, its really all about the sauce in my opinion.
