Heat oven to 400° F.
In a large skillet, over medium heat, fry the bacon until crisp, about 6 minutes. Transfer to a paper towel-lined plate. Discard the drippings. Wipe out the skillet and heat the oil over medium-high heat.
Season the chicken with 1/2 teaspoon of the salt and 1/4 teaspoon of the pepper. Cook until golden brown, about 3 minutes per side. Transfer to a baking dish and roast until cooked through, about 8 minutes.
Meanwhile, add the onion to the skillet and cook, stirring occasionally, until soft, about 8 minutes. Add the edamame and corn and cook, stirring occasionally, until heated through, 2 to 3 minutes. Break the bacon into pieces and add them to the skillet. Stir in the remaining salt and pepper. Spoon onto individual plates and serve with the chicken.
Shortcut: Omit the bacon to save time and cut fat.
