Start your Valentine's Day meal with a creamy and cheesy spinach and artichoke dip. With the help of a food processor, you can easily blend the ingredients together for a smooth and flavorful dip. Combine spinach, artichoke hearts, cream cheese, sour cream, mayonnaise, garlic, Parmesan cheese, and a pinch of salt in the food processor. Blend until well combined and creamy. Transfer the mixture to a baking dish, sprinkle with mozzarella cheese, and bake until bubbly and golden. Serve the dip with tortilla chips or toasted bread slices.
