The first time I made this was as a birthday surprise and now it has become our family’s celebratory signature The combination of seafood and cheesy sauce always wins the table over
Ingredients

- Parsley: Freshly chopped gives color and a pop of freshness
- Salt and black pepper: Heighten all the flavors Use sea salt and freshly ground pepper

- Make the Cheese Filling:

Picking fresh shrimp always reminds me of shopping with my grandmother in the old market She always insisted on the most fragrant parsley to finish the dish and now I never skip the garnish
