This recipe uses egg noodles which you can either buy fresh at the grocery store (often found near the tofu) or dried. If you don't have any on hand, spaghetti will work just fine.
Don't rinse the noodles after cooking; leaving them will keep them just starchy enough to help thicken the sauce so it clings better to the shrimp and veggies.
Cook the shrimp just until pink in step 3. It will cook further once it's added back in the final step.
Store leftovers in an airtight container in the fridge for up to 3 days.
Reheat in the microwave or in a saucepan until heated through.
