In nonstick Dutch oven or large saucepan, combine onion, garlic and water. Bring to a boil. Reduce heat to low; cover and cook 10 minutes or until onion is tender and translucent, stirring occasionally and adding additional water if necessary to prevent scorching.
Meanwhile, cook linguine to desired doneness as directed on package. Drain.
Add all remaining ingredients except linguine to onion mixture. Bring to a boil. Reduce heat; cover and simmer 10 minutes to blend flavors. Remove and discard bay leaf. Serve sauce over linguine.
