Add the onion and olive oil to a large pan and saute for about 5 minutes.
Add in the garlic and saute for about 1 additional minute.
Add in the shrimp, salt, red pepper flakes, and black pepper.
Saute for 3-4 minutes or until the shrimp begin to cook.
Add in the chicken broth, lemon zest, and juice.
Cook until the shrimp are completely cooked through, about 2-3 more minutes.
Add in the zucchini noodles, parsley, chives, and parmesan, then toss to combine.
You can cook down the zucchini to soften, or just saute it for a minute or so to retain some crunch.
Serve with extra parmesan and enjoy!
