Pat the chicken breast and prawns dry with paper towels to ensure a good sear, then season both with sea salt, black pepper, and smoked paprika.
Heat the extra virgin olive oil in a large cast-iron skillet over medium-high heat.
Add the chicken cubes to the skillet and cook for 5-6 minutes until golden brown and cooked through, then remove and set aside.
In the same skillet, add the prawns and sear for 1-2 minutes per side until they turn pink and opaque, then remove and set aside with the chicken.
Lower the heat to medium and add the ghee to the skillet. Once melted, add the minced garlic, sliced zucchini, and diced red bell pepper.
Sauté the vegetables for 3-4 minutes until they are tender-crisp and the garlic is fragrant.
Return the chicken and prawns to the skillet, tossing everything together to coat in the garlic butter sauce.
Turn off the heat and stir in the fresh lemon juice and chopped parsley before serving immediately.
