1. In a pan, on medium heat, stir spinach and garlic until spinach is bright green.
Set spinach aside in a bowl to cool a bit. Press spinach to drain as much liquid as possible.
2. In pot on low-medium heat, melt cream cheese until easy to stir. Add mayo, parmesan cheese, artichoke hearts, salt and pepper, and half the mozzarella cheese. Mix well. Add spinach. Mix.
3. Pour mixture into a small baking dish. Add remaining mozzarella cheese, and a little pepper.
Bake 350 for 20 minutes, and when the top is starting to be brown.
