In a bowl, toss together the the butternut squash, mushrooms, red onion, poultry seasoning and olive oil.Transfer the contents of the bowl onto the parchment-lined baking pan, and roast for 15-17 minutes, flipping the contents of the pan around once halfway through.

For the optional sage leaves, stir the sage leaves and olive oil together in a bowl until the herbs are well coated. Bake them in the oven at 400°F (200°C) for 7-8 minutes until crisp, but not completely dried out. As they cool sprinkle with salt to taste.
Toss the baguette slices in a bowl with the cinnamon, coriander, and olive oil until well coated.
Arrange the bread slices on a parchment paper-linked baking pan and bake for 7 minutes, or until crisp and lightly golden.
When the bread comes out of the oven rub with the garlic cloves and sprinkle with salt to taste.
