Preheat your oven to 375°F (190°C).
Halve the pears and scoop out the cores to create a small well in each half.
Place the pears cut-side up in a baking dish. Drizzle with olive oil, and fill each center with crumbled feta and chopped cranberries.
Bake for 15-20 minutes, until the pears soften and the feta starts to melt.
Remove from the oven, drizzle with honey, and sprinkle with fresh thyme. Season with salt and pepper.
Add chopped walnuts if desired for an extra crunch.
