Preheat the oven to 180 degrees C/ 350 F and line a large baking tray with parchment paper. Alternatively, you can lightly grease it with olive oil.
Add the broccolini, red onion, bell peppers, carrots, zucchini, sweet potatoes and chickpeas to a large mixing bowl. Stir together well, then add the olive oil, dried thyme and oregano, tamari, garlic, cumin, garlic powder and paprika, and mix together once again.
Transfer the vegetables and chickpeas to the baking tray, spreading them out into a single layer. Bake in the preheated oven for 35-40 minutes, until all of the vegetables are cooked through and crispy.
