Cut the focaccia bread in half on a horizontal axis, then cut into 10 1’’ x 3'’ slices. Toast the bread under a boiler, or in a toaster, until slightly golden. Set aside.
Divide and spread the ricotta cheese onto the focaccia toasts. Season lightly with salt, then layer the salami and nectarine. Skewer with a toothpick. Repeat until all of the toasts are made.
Plate the appetizer and drizzle with balsamic glaze, and sprinkle with basil. Serve warm or chilled.
