Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Slice the zucchini into half-moons and chop the red bell pepper into bite-sized pieces.
Toss the vegetables on the baking sheet with olive oil, dried oregano, and half of the sea salt and black pepper.
Roast the vegetables for 15-18 minutes until they are tender and slightly caramelized at the edges.
While vegetables roast, heat the ghee in a large skillet over medium heat.
Add the minced garlic to the skillet and sauté for 1 minute until fragrant, being careful not to burn it.
Increase heat to medium-high and add the prawns, seasoned with the remaining salt and pepper. Cook for 2-3 minutes per side until pink and opaque.
Turn off the heat and stir in the fresh lemon juice, tossing the prawns to coat them in the garlic butter sauce.
Place the warm cooked quinoa in a bowl, top with the roasted vegetables, and finish with the garlic butter prawns.
