In a small saucepan, combine Frozen Spinach (1 cup) and Artichoke Hearts Packed in Water (1 1/2 cup) over medium heat, frying for 1 minute.
Season with Salt (to taste) and Ground Black Pepper (to taste). Add the Cream Cheese (8 ounce) and stir until melted.
Remove from the heat and stir in the Sour Cream (1/4 cup), Mayonnaise (1/4 cup), Grated Parmesan Cheese (1/3 cup), Garlic Powder (1 teaspoon), and Crushed Red Pepper Flakes (1 teaspoon). Taste and adjust seasoning if needed.
Serve while it’s still warm, or reheat before serving. Great with crackers, bread, or low-carb options like veggie sticks.
