Preheat your oven to 350°F (175°C).

Sauté the spinach in a skillet over medium heat until wilted (about 2 minutes).

In a large bowl, mix together sautéed spinach, drained artichoke hearts, cream cheese, sour cream, Parmesan cheese, and garlic powder until well-combined.

Stir in hot sauce to taste.

Transfer the mixture to an oven-safe dish and bake for 25 minutes or until golden brown and bubbly.

Let cool slightly before serving with tortilla chips or bread slices.
