1. Slice chicken breasts into approximately 12–15 thin, ﬂattened strips. (A meat mallet can help you pound the cutlets.)
2. Lay one slice of pastrami on each ﬂattened chicken strip. Roll up jelly-roll fashion and fasten with a toothpick. Place all the chicken rolls into a pan.
3. Combine ketchup, mayonnaise, and apricot jam in a bowl. Pour sauce over cutlets.
4. Bake, covered, for one hour.
5. Preheat oven to 350 degrees Fahrenheit.
