Place the cherry tomatoes on a baking tray, drizzle with olive oil and sprinkle with salt and black pepper. Roast in the preheated oven for 15-20 minutes until softened and slightly charred. Set aside.
Spaghetti
Cook the spaghetti according to the packet instructions. Drain and set aside.
Spicy White Bean Sauce
While the spaghetti is cooking, prepare the spicy white bean sauce. In a large frying pan or wok, heat the olive oil over medium heat. Add the onions, garlic, red chilli and red peppers, and sauté for 5-7 minutes until softened.
Add the chopped tomatoes, cayenne pepper and paprika, and cook for a further 5 minutes until the tomatoes have broken down and the sauce has thickened.
Add the drained and rinsed pinto beans to the pan, along with the sliced olives, lime juice and fresh parsley. Cook for a further 2-3 minutes until the beans are heated through. Season with salt to taste.
Garlic Prawns
In a separate pan, heat the olive oil over medium-high heat. Add the raw prawns, minced garlic and white pepper, and cook for 2-3 minutes on each side until the prawns are pink and cooked through.
Plate up
To serve, divide the spaghetti between four plates, top with the spicy white bean sauce and garlic prawns, and sprinkle with fresh parsley. Serve with the roasted cherry tomatoes on the side.
