To make the dressing, place peanut butter, soy sauce, sriracha and lemon juice in a bowl.
Whisk thoroughly till smooth. Your dressing is ready.
In a small mason jar, place the carrots at the bottom and proceed making layers alternating between veggies, herbs and noodles.
Once you have assembled layers covering half the jar, spoon the dressing over the top most layer.
