3 red onions, halved
15 roma tomatoes, halved
2 green bell peppers, halved and seeded
2 red bell peppers, halved and seeded
1 bunch green onions

Drizzle all the vegetables lightly with oil, then place on a preheated grill. Char them until visible grill marks appear and the vegetables are tender, flipping them as necessary. Cool vegetables until they can be handled, then cut into a large dice. Toss all together and season with additional oil, kosher salt, and cracked black pepper.
