OK.......This is the same recipe I use for Split pea soup when being made from fresh ingredients.

Split Pea Soup

1 package white sauce Mix (2.75 ounces)
1 tablespoon chicken bouillon granules
2 teaspoons Imitation bacon bits
2 teaspoons dried celery flakes
2 teaspoons dried minced onion
1 teaspoon dried parsley flakes
1 1/2 cups dried split green peas
1 medium bay leaf(optional)

Assemble

1) Pour sauce Mix into wide-mouth pint jar. In small bowl stir together bouillon granules, bacon bits, celery flakes, onion and parsley flakes. Pour into jar to make second layer. Add peas; place bay leaf on top. Seal with lid.

2) Print this on a Gift Tag: "Empty contents of jar into large saucepan or dutch oven. Add 6 cups water. Heat to boiling, stirring often. Reduce heat. Cover and simmer for 2 hours or until peas are tender, stirring frequently to prevent peas from sticking. Remove bay leaf before serving. Serve soup with dollop of sour cream and bacon bits, if desired. Makes 6 servings."

3) Attach gift tag and decorate jar as desired.

Recipe to attach:

Combine the following:
Cookie mix
1 beaten egg
1/2 cup butter-flavored shortening (I used butter)
Shape dough into walnut-sized balls. Place two inches apart on greased cookie sheet. Bake at 350� for 10 to 12 minutes. Makes about 24 cookies.

You could probably use any kind of cookie recipe, just using the dry ingredients and then attaching a card with the wet stuff along with directions....
At one time these were great sellers at craft shows....
