Drain the artichokes and spinach well, then add them to the bowl of a large food processor fitted with an S-shaped blade. Add in the rest of the ingredients, and use the "pulse" button to combine into a chunky dip.
The texture of this dip is completely up to your personal preference. You can leave it chunky, for a slightly different taste in each bite, or process longer for a more uniform-looking dip! I added a bit of honey to mine, and processed again, for a slightly more balanced flavor and smoother texture.
For best flavor, allow to chill for at least 4 hours before serving, and store any leftovers in the fridge for up to 3 days.
