Spinach Artichoke Dip

This seems to be a popular holiday dip so decided I must make it! Now most of the recipes seemed to have mainly a mayo base, but since I'm not a huge fan of mayo I decided to change it up a bit.

10 oz frozen chopped spinach (thawed and drained)
14 oz can artichoke hearts (chopped)
6 oz cream cheese
1/4 cup mayo
3/4 cup sour cream
1 1/2 cup parmesan cheese
1 1/2 cup italian four cheese blend (mozzarella, mild cheddar, provolone, & asiago)
1 tsp garlic powder

Directions
1. Preheat oven to 350
2. Combine spinach and chopped artichoke hearts in a small baking dish
3. In a mixing bowl heat the cream cheese in the microwave for 1 min 30 secs
4. Add the mayo and sour cream to the cream cheese. Mix well.
5. Add this mixture to the baking dish (with the spinach and artichokes), add the garlic powder and cheeses (saving 1/2 cup of each cheese).
6. Mix all ingredients well in the baking dish
7. Top the dip with the rest of the cheese (1/2 cup parmesan, 1/2 cup italian blend)
8. Bake for 30 minutes

Enjoy! This dish went over very well at my in-laws, it was gone in a matter of minutes! It's incredibly easy and very yummy, you can't go wrong!
