Drop the garlic in a food processor while it's running; process until minced. Stop the machine and add the remaining ingredients, along with some of the oil from the tomatoes. Stop the machine, scrape down the sides and check for consistency; add more oil if necessary. Process until smooth.
This makes a great spread on crusty Italian bread. It's also a great addition to soups and stews and makes a nice pasta sauce (thin with a bit more oil). Makes about 1-1/4 cups.
