Recipe: Stuffed Baby Peppers From Giada at Home   4 to 6 servings   My mother always loved to serve stuffed vegetables; she stuffed zucchini, potatoes, onions, and, of course, all kinds of peppers. It may have been her way of getting us to eat our vegetables, but we loved them so much we ate them right out of the fridge the next day. I've used pancetta in the filling, but this is an easy recipe to vary and you could certainly substitute ground beef, sausage -- almost anything savory that you like. These taste better the longer they sit, so they make great leftovers.   Vegetable oil cooking spray 2 tablespoons olive oil 3 ounces thinly sliced pancetta, finely chopped 1/2 medium onion, finely chopped 3/4 cup whole-milk ricotta cheese 1/3 cup freshly grated Parmesan cheese 1/3 cup frozen petite peas, thawed Salt and freshly ground black pepper 24 (2- to 3-inch long) baby peppers   Place an oven rack in the center of the oven and preheat the oven to 350°F. Spray a rimmed baking sheet with vegetable oil cooking spray. Set aside.   In a medium skillet, heat the olive oil over medium-high heat. Add the pancetta and cook, stirring frequently, until brown and crispy, 5 to 7 minutes. Using a slotted spoon, remove the pancetta and drain on paper towels. Add the onion to the pan and cook until translucent and soft, about 5 minutes. Set aside to cool for 10 minutes.   In a medium bowl, combine the onion, pancetta, cheeses, and peas. Season with salt and pepper.   Using a paring knife, cut ½ inch from the stem end of each pepper. Remove the seeds and veins. Using a small dessert spoon, fill each pepper with the cheese mixture. Place the filled peppers on the prepared baking sheet and bake for 15 to 18 minutes, until the peppers begin to soften and the cheese is warmed through. Cool for 10 minutes.   Arrange the peppers on a platter and serve.
