Cool the tomatoes. The tomatoes can be covered with olive oil and stored in the refrigerator for up to 1 month.
For the slow-roasted butternut squash: Preheat the oven to 400 degrees F. Place the squash in a large bowl and drizzle with the oil and season with salt and pepper. Toss. Spread the squash in a single layer on a baking sheet and roast until tender and golden on the edges, about 20 minutes.
For the kale pesto: Combine the broccoli rabe, kale, garlic and stock in a food processor and pulse until chopped. Add the almonds and cheese and season with salt and pepper. With the motor running, slowly add the oil.
For the pizzas: Put pizza stones or perforated pizza pans in the oven to heat up and preheat the oven to 450 degrees F. Spread the shells or dough with 1/3 cup of the kale pesto to within 1/8 inch of the edges. Divide 1/3 cup of the slow-roasted butternut squash and 1/4 cup of the roasted tomatoes evenly among the shells. Sprinkle with the mozzarella. Bake until the edges are deeply browned and the cheese is bubbly, 8 to 10 minutes. Sprinkle the pizzas with basil and oregano and scatter the shaved Parmesan over the top. Drizzle with oil and enjoy.
