Line a rimmed baking sheet with parchment paper and arrange cubes of cornbread in a single layer. Bake for 10 minutes, or until lightly browned. Remove and place cubes in a large salad bowl. (Leave oven on.)
Line the same baking sheet with a fresh sheet of parchment paper. Spread delicata squash over the bottom in a single layer; sprinkle bacon pieces over the top. Season with salt and freshly ground black pepper. Bake for 30 to 40 minutes, or until bacon is browned and squash is tender – stir after about 20 minutes. Remove from oven and add to cornbread in salad bowl; toss to combine.
Meanwhile, melt butter in a large skillet over medium heat. Add sage leaves; cook and stir until sage begins to crisp and butter smells slightly nutty. Add to cornbread and toss to combine.
In the same skillet (no need to wash it out) add water or broth, black eyed peas, and kale. Cook and stir for 4 to 6 minutes, or until peas are thawed and warm and kale has wilted slightly. Remove from heat and drizzle with olive oil, a splash or two of red wine vinegar, and salt and freshly ground black pepper to taste. Add to cornbread mixture and toss to combine. Serve.
A quarter round of my skillet cornbread is just the right amount for this salad, but you can use any cornbread recipe you like.
