1) Preheat the oven to 200°C. Line a baking tray with foil.
2) Place the chopped greens on the foil. Drizzle with olive oil and gently toss. Top the greens with another piece of foil and seal shut. Roast the greens until tender, about 20 minutes.
3) lace the bread cubes, sun-dried tomatoes, vinegar, extra-virgin olive oil, salt, and pepper in a large bowl. Gently toss. Add the roasted greens and toss to combine.
