I started a Relief Society interest group (Cooking) and we shared recipes and cooking techniques. One time we focused on beans. Here is one of the recipes that we sampled.

¾ Cup shortening
2 Cups brown sugar
2 eggs
¼ Cup salad dressing
½ teaspoon salt
1 teaspoon soda
1 teaspoon vanilla
1 Tablespoon peanut butter
¾ Cup cooked mashed pinto beans
3 – 4 Cups flour

Cream shortening, sugar, and eggs. Add salad dressing, salt, vanilla, peanut butter, and beans. Add soda and enough flour to make a dough stiff enough to handle. Chill until ready to use. Roll out, cut, and decorate as desired. Bake at 350 degrees for 15 minutes. Can decorate with frosting after cooled.
