Mix sour cream, mayo, cream cheese, Parmesan cheese, and garlic until smooth. Stir in artichoke hearts, spinach and Mozzarella Cheese.
Heat ½" oil in a sauce pan on medium heat.
Once oil is hot enough (place hand over pan, above oil, to feel heat), prepare the taquitos. Add a few tablespoons of spinach/cheese mixture to the center of a tortilla and spread out. Roll up and set seam side down in oil using tongs. Cook until golden brown on both sides.
Repeat until all the tortillas are filled, rolled and fried.
