Heat Wolf Gourmet Countertop Oven to Convection/Roast 375°F. Line the Wolf Gourmet baking pan with parchment paper and place plums in the pan cut sides up.
Drizzle with olive oil and honey. Roast until tender and juices begin to release, 5-10 minutes.
Once complete, toast the bread until just golden. Spread 1/3 cup ricotta on each slice. Arrange plums on top of ricotta and spoon juices over.
Drizzle with additional olive oil and honey. Season to taste with salt and pepper. Finely grate orange zest over each slice and serve.
