Cheesy Spinach and Artichoke Dip

I don't know that I've posted an appetizer before! Well...then it's about time. I make this a lot around the holidays when I need to bring a dish to a party. It's best heated up, but tastes good as it cools as well.

Ingredients:
14 oz artichoke hearts, drain, fine chop
10 oz frozen chopped spinach, thaw, drain well
3/4 c Parmesan
3/4 c light mayo (this part is very difficult for me as I despise mayonnaise)
1/2 c shredded mozzarella
1/2 t garlic powder

Directions:
Heat oven to 350
Mix ingredients well
Spoon into a pie dish
Bake 20 minutes

Easy as that!
