The only recipe that I could find was in My Great Recipes was a recipe for Sesame Swiss Puffs - I hope this is the one you are looking for.

SEASAME SWISS PUFFS

For 60 puffs you will need:
1 cup water
1/3 cup butter or margarine
1/2 tsp salt
1 cup all purpose flour
1 tsp Dijon-style mustard
4 eggs
1/2 cup shredded Swiss cheese
1/2 cup grated parmesan cheese
1 egg yolk
1 tbsp mils
2 tbsp sesame seeds
about 1 1/2 cups Clam-Cheese Filling (recipe follows)

Measure water into saucepan and add butter and salt. Heat until butter melts, then bring to a boil. Immediately add flour and stir over low heat until a ball of dough forms and cleans sides of pan, about 1 minute.

Remove from heat. Beat in mustard and eggs, one at a time. Beat until smooth.

Stir in Swiss and Parmesan cheeses.

Shape a heaping teaspoonful of the dough at a time into little mounds on greased cookie sheet, 2 inches apart.

Mix egg yolk and mild. Brush topes of dough with mixture. Sprinkle with sesame seeds.

Bake at 375 degrees F for 25 minutes or until puffy and golden.

Cool, split, and fill each puff with 1teaspoon of filling. Serve immediately.
