Preheat the oven to 400 degrees. Make the croutons: Toss the bread cubes with the olive oil, cheese and half of the scallions on a rimmed baking sheet. Bake until the cheese melts, about 5 minutes. Use a spatula to flip and stir the croutons to coat in the melted cheese. Bake until golden brown and crisp, about 6 more minutes.
Meanwhile, make the dressing: Whisk the mayonnaise with the chili sauce, the remaining scallions, half of the pickles, and the pickle juice. Toss the kale and iceberg lettuce with half of the dressing in a large bowl. Divide among bowls and top with the tomatoes, roast beef, turkey, croutons and the remaining pickles. Serve with the remaining dressing.
