In a 3-cup jar or container with a tight-fitting lid, layer the beans, lentils and peas. In a small resealable plastic bag, combine the tortellini, parsley, bouillon, garlic, thyme and salt. Place bag in jar. Replace lid and store in a cool dry place. Yield: 1 batch (about 2-1/4 cups).
To prepare soup: Remove bag of tortellini and seasonings; set aside. Rinse the beans, lentils and peas; drain. Place in a Dutch oven. Add 8 cups water. Bring to a boil. Reduce heat; cover and simmer for 45-60 minutes or until beans are tender.
Stir in the tortellini and seasonings, broth, tomatoes, carrots and celery. Bring to a boil. Reduce heat; simmer, uncovered, for 8-10 minutes or until pasta and vegetables are tender. Serve with cheese if desired. Yield: 15 servings (3-3/4 quarts).
