Peel off corn husks and hairs. Remove corn from cob and place in food processor. (Just add drained corn to food processor if using canned corn)
Add all garlic and chick peas to the food processor bowl.
Turn processor on while slowly drizzling olive oil through the chute, repeat with lemon juice.
Process the corn mixture until you have a hummus like texture (this should not take very long at all, perhaps 30 seconds to 1 minute)
Scoop into a serving bowl and top with green onions.
