Preheat your oven to 350 degrees.

In a medium bowl, beat together the thawed spinach and softened cream cheese until well combined.

Add minced garlic, salt, onion powder, chili powder, pepper, Italian seasoning, parmesan cheese, and mozzarella cheese to the mixture. Mix until creamy and smooth.

Unroll the pizza crust onto a sheet of parchment paper. Use a pizza cutter to slice the dough into a large tree-shaped triangle and two smaller triangles.

Move the smaller triangles to a second sheet of parchment paper, ensuring the straight edges are touching, to form a second triangle.

Spread the spinach dip evenly across the second triangle. Carefully flip the first triangle over on top, creating layers of dough with the spinach dip in between.

Make cuts from the center to each side of the dough, leaving about an inch intact at the center. Cut every inch or so to create slices.

Twist each 'slice' of dough upwards. For the shorter pieces at the top, twist halfway around; for the longer pieces at the bottom, make two to three full twists.

Bake the breadsticks for 30-35 minutes, or until they are golden brown and fully cooked through.

While the breadsticks are baking, melt the butter and stir in garlic salt and seasoning. Once the breadsticks are out of the oven, brush this mixture over the tops and serve warm.
