Measure the chicken bouillon granules into a 1 pint jar. Top with 1/3 cup of instant rice, red lentils, dried parsley, pepper, poultry seasoning, 1/3 cup of rice and then the green lentils on top. Seal with a lid and ring for gift giving.
To make the soup, bring the butter and water to a boil in a large pot. Pour in the contents of the jar and add celery and chicken if using. Bring to a boil, then reduce heat to medium and simmer until the lentils are tender, about 30 minutes.
