In an ungreased cast iron or non-stick skillet or griddle heat unpeeled garlic cloves over medium heat for 10 to 15 minutes or until skins of garlic are blackened (turn cloves occasionally to blacken evenly) and cloves are soft. Remove from skillet; cool slightly. Peel cloves and mash well with a fork; set aside.
In a large saucepan cook onion and celery in hot oil about 5 minutes or until tender. Add mashed garlic, undrained peas, tomatoes, water, cumin and red pepper. Bring mixture to boiling; reduce heat. Cover and simmer for 15 minutes. Uncover and simmer about 5 minutes more or to desired consistency.
Combine rice and parsley; mix lightly. Serve peas over rice. Makes 6 servings.
