In a large bowl, combine vegetables, olive oil, herbes de Provence, salt, and black pepper, tossing until well coated. Spread in a single layer on prepared baking sheet.
Bake until vegetables are tender, 30 to 35 minutes. Let cool slightly. Chop finely.
In a medium bowl, combine cream cheese and roasted vegetables, stirring well.
Spread 3 tablespoons cream cheese mixture on each of 3 bread slices. Top each bread slice with a plain bread slice. Spread remaining 3 bread slices with remaining cream cheese mixture. Place each, filling side down, atop each plain bread slice.
Using a serrated knife, trim crusts from sandwiches with a gentle sawing motion. Discard crusts. Cut each sandwich vertically into 6 slices.
Notes
*For testing purposes, we used Pepperidge Farm Farmhouse Whole Wheat Bread.
