Bacon fruit tastes great, with cheese fruit.

I knew a woman who put dates on bread when I was young child. It looked to me like squashed bugs 😬 Your question triggered my memory of this.

Apple & cinnomen toasties would be my choice.

Blueberry's are good if they are homemade

strawberries are nice on rye bread

Marmalade? Lemon curd?
