Toss shrimp with garlic, chili flakes, and salt and pepper.
Preheat olive oil and butter in a large pan over medium heat.
Add shrimp to the pan and cook for 4-6 minutes or until shrimp are just pink.
Remove from the heat and stir in parsley.
Notes
Keep leftover shrimp in an airtight container in the refrigerator for up to 3 days. Enjoy cold on a salad, or tuck them into a low carb wrap for lunch.
