Preheat the oven to 450°.

In a medium bowl, knead the sausage meat with the cooked rice. Fill the peppadew peppers with the meat mixture, pressing to compact it.

Arrange the peppadews meat side up on a lightly oiled baking sheet; lightly press down on them so they don't wobble. Drizzle the peppadews all over with olive oil and sprinkle with the grated Parmigiano-Reggiano cheese.

Bake the peppadews in the upper third of the oven for about 15 minutes, until the sausage meat is cooked through. Transfer the peppadews to a platter and serve warm or at room temperature.

MAKE AHEAD The unbaked stuffed peppadews can be refrigerated overnight. Bring to room temperature before baking. The baked stuffed peppadews can be covered loosely and kept at room temperature for up to 2 hours.
