Preheat the oven to 400°F.
Bring a pot of salted water to a boil. Cook the gluten-free pasta,
reducing the package cooking time by 2 minutes. Drain and set aside.
Arrange the cherry tomatoes, zucchini, and bell peppers on a lined baking tray. Drizzle with olive oil and season with paprika, thyme, and oregano. Roast for 15 to 20 minutes, or until the vegetables are tender and lightly caramelized. Set aside.
Heat the remaining olive oil in a pan over medium heat. Sauté the crushed tomatoes for about 2 minutes, then add the stock and simmer for another 2 minutes.
Add the pre-cooked pasta to the sauce and toss gently, allowing it to absorb the flavors.
Turn off the heat and fold in the roasted vegetables, fresh basil, and spinach to the pasta.
Season with salt and pepper. Finish with a light drizzle of fresh lemon.
