Toast the pistachios in a dry skillet over a medium-high heat until fragrant, about 2 minutes. Set aside to cool. Chop coarsely. Cut each fig in half crosswise and place the fig pieces on a serving dish, cut side up. Make a small indentation into the cut side of each fig half with a small spoon or your finger. Put 1/2 teaspoon of the ricotta cheese onto each piece of fig and top with a pistachio. Drizzle with honey and serve.
