Egg And Chicken Liver Canape

Melt the butter in a skillet over medium heat. Add the chicken livers and onion and cook, stirring frequently, until the livers are cooked and the onion is soft. Transfer the livers and onion to a bowl.

Add the hard-boiled egg to the bowl. Mash the livers and egg together with a fork. Stir in the mayonnaise, ketchup, onion salt, and pepper until the mixture is the desired consistency, adding additional mayonnaise if needed.

Spread the egg and chicken liver mixture on party rye bread or crackers. Store leftovers in a covered container in the refrigerator for up to 2 days.
