In a mixing bowl, combine warm water, yeast, and sugar. Let it sit for 5 minutes until frothy.

Add flour, salt, and olive oil to the yeast mixture. Mix until a dough forms.

Knead the dough on a floured surface for about 5 minutes until smooth. Place in a greased bowl, cover, and let rise for 1 hour.

In a bowl, mix together mozzarella, cream cheese, Parmesan, garlic powder, and Italian seasoning until well combined.

Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper.

Once the dough has risen, punch it down and roll it out on a floured surface to about 1/2 inch thick.

Cut the dough into strips about 1 inch wide and 6 inches long. Place a tablespoon of cheese filling in the center of each strip and fold the dough over, sealing the edges.

Shape the filled strips into bone shapes by pinching the ends and making them thicker.

Place the shaped breadsticks on the prepared baking sheet. Brush with olive oil and sprinkle with sea salt.

Bake in the preheated oven for 15 minutes or until golden brown.

Remove from the oven and sprinkle with dried parsley before serving.
