Spinach Artichoke Hummus

I loved spinach and artichoke dip before I had to stop eating dairy, and believe it or not I find this satisfying enough.

1 can chickpeas, drained and rinsed
1 clove garlic
2 tbsp tahini
2 tbsp lemon juice
olive oil to taste
salt and cayenne to taste
1/2 10oz pack frozen spinach, thawed, squeezed, drained, and coarsely chopped (or use about 4 cups fresh)
1 14oz can artichoke hearts, drained, coarsely chopped
1/4 c. asiago or parmesan cheese grated if you can

I put everything in the blendtec on the soup setting. I don't bother chopping the artichokes or the spinach.
