Step 1: Prepare the Filling

1. In a mixing bowl, combine the cream cheese, mozzarella, and cheddar cheese. Stir until smooth.
2. Add the mayonnaise, Dijon mustard, garlic powder, onion powder, paprika, salt, and black pepper. Mix well.
3. Gently fold in the crab meat, lemon juice, and chopped parsley. Be careful not to break the crab apart too much.

Step 2: Assemble the Crescent Rolls

1. Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
2. Unroll the crescent dough and separate it into 8 triangles.
3. Place a spoonful of the crab and cheese filling onto the wider end of each triangle.
4. Gently roll the dough, starting from the wide end and working toward the tip, enclosing the filling inside.
5. Arrange the filled rolls on the prepared baking sheet, spacing them slightly apart.

Step 3: Bake to Golden Perfection

1. Brush the tops of the crescent rolls with the beaten egg for a shiny, golden finish.
2. Bake for 12-15 minutes, or until the rolls are puffed and golden brown.
3. Remove from the oven and let them cool for 5 minutes before serving.

Step 4: Serve & Enjoy

1. Garnish with extra chopped parsley for a fresh touch.
2. Serve warm with your favorite dipping sauce, such as garlic aioli, honey mustard, or a light lemon butter sauce.
