Preheat oven to 350 degrees.
Place the cream cheese, greek yogurt, spinach, and artichoke hearts in a 8-inch ceramic casserole dish. Cook for 30 minutes.
Stir together until cream cheese, yogurt, and vegetables are all blended.
Stir in the Romano cheese, granulated garlic, onion powder, crushed red pepper, and salt. Taste for salt and add more, if needed.
Cook for another 30 - 40 minutes or until hot and bubbly. Serve hot or warm with bread, pita, or pretzels.
