Chop the ends off your zucchini and then turn into "zoodles" using a spiralizer. You can get an affordable hand-held spiralizer or counter-top model off Amazon or if you have a KitchenAid mixer you can buy their super duper spiralizer attachment.
Melt butter in a large skillet over medium heat. Add the shrimp, garlic and red pepper flakes. Stirring occasionally, cook for about 2-3 minutes until the shrimp are pink.
Stir in chicken stock and lemon juice; season with salt and pepper to taste. Turning the heat down, bring to a simmer and stir in the zucchini noodles. Cook for about 1-2 minutes.
Serve immediately and garnish with parsley (and parmesan if desired!)
