In a mixing bowl, combine shrimp with 2 tablespoons olive oil, honey, lime juice, salt, pepper, and red pepper flakes. Toss to thoroughly coat. Marinate for 15 minutes.
Spiralize zucchini and set aside.
Place a cast-iron skillet over medium heat with 1 tablespoon of butter. Once the butter has melted, add the minced garlic - cooking until fragrant, approximately 1-2 minutes. Add in the shrimp without the marinade. Cook each side for 2 minutes. Add the marinade/sauce and cook for 1-2 more minutes to allow the sauce to thicken.
Transfer shrimp and sauce to a plate. In the same skillet, add 1 tablespoon of olive oil. Once heated, add the zucchini noodles and cook until tender, about 2-3 minutes. Add the shrimp back to the skillet to warm.
Garnish with freshly chopped parsley and serve immediately. If you love the taste of lime juice, I recommend squeezing a little extra over the top of the dish prior to garnishing.
*Marinating shrimp is optional. But like with any meats - marinading makes everything better!
