Preheat the oven to 400 degrees Fahrenheit. Use a bread knife to cut the bread into 12 equal slices.
Line two baking trays with parchment paper.
Place the halved pears in a bowl, then toss them in the honey, cinnamon, and salt.
Spread the fruit in a single layer on one of the baking trays.
Bake for 12 minutes, until soft and slightly golden brown
Meanwhile, use a bread knife to slice the bread into 12 individual crostini.
Place them on the second prepared tray and bake them for 8 minutes (same oven temperature).
Allow the pears to cool just enough to handle, then thinly slice them.
Spread a layer of ricotta cheese on the toast, then top with some pears.
Garnish with the toasted walnuts and a touch of honey on top if desired.
Serve immediately and enjoy.
