Chop the artichoke hearts and spinach in your food processor until chunky. (You can chop them with a knife if you'd prefer.) Pour the chopped artichokes and spinach into a large bowl and add the remaining ingredients. Mix well.
Scoop the spinach dip into an ovenproof baking dish and bake in the preheated oven for 20 minutes, or until it is warmed through and starting to bubble at the edges. Serve warm with bread or veggies to dip.
