Sort and wash peas. Bring garlic and 3 cups water to a boil in medium saucepan. Add peas; return to a boil. Cover, reduce heat, and simmer 25 minutes. Stir in 1/4 tsp. salt; cook 15 minutes or until tender. Drain.
Combine peas, olive oil, next 2 ingredients, and remaining 1/4 tsp. salt in a food processor; pulse 5 to 7 times or until smooth, stopping to scrape down sides as needed. Serve at room temperature.
