Preheat your oven to 375°F (190°C).
In a medium mixing bowl, combine chopped spinach, cream cheese, sour cream, Parmesan cheese, and garlic powder.
Season the mixture with salt and pepper to taste, then set aside.
Unroll the crescent roll dough on a lightly floured surface and separate it into triangles.
Place a spoonful of the spinach dip mixture on the wide end of each triangle, then roll up towards the tip.
Arrange the rolled bites on a baking sheet lined with parchment paper, spacing them apart.
Bake in the preheated oven for 12-15 minutes, or until golden brown.
Remove from the oven and let cool slightly before serving.
