Ingredients

1. 24 shucked oysters, on the half shell
2. 4 thick slices of smoky bacon
3. 2 tablespoons unsalted butter
4. 1/4 cup finely diced red bell pepper
5. 1/4 cup finely diced green bell pepper
6. 1/4 cup finely diced onion
7. Salt and freshly ground pepper
8. 1 tablespoon chopped flat-leaf parsley
9. Lemon wedges, for serving

1. Arrange the oysters on a large baking sheet and refrigerate. In a medium skillet, cook the bacon over moderate heat until crisp, about 5 minutes. Drain on paper towels and cut crosswise into 1-inch lengths.
2. Melt the butter in a saucepan. Add the bell peppers and onion; cook over moderately high heat, stirring often, until softened, 5 minutes. Season with salt and pepper and stir in the parsley. Let cool slightly, spoon over the oysters and top with the bacon.
3. Light a grill or preheat the oven to 500°. Using tongs, transfer the oysters to the grate and grill over a moderately low fire for 7 to 10 minutes, or until just cooked through. Alternatively, roast the oysters on the baking sheet in the oven. Transfer to a platter and serve at once with lemon wedges.
