Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Place the diced zucchini, red bell pepper, and red onion on the baking sheet; drizzle with half of the olive oil and season with a pinch of the sea salt and black pepper.
Toss the vegetables to coat evenly and roast for 18-20 minutes until the edges are golden and tender.
While the vegetables roast, heat the remaining olive oil in a large skillet over medium-high heat.
Add the ground chicken to the skillet, breaking it into small crumbles with a spatula, and cook until browned and no longer pink.
Stir in the minced garlic, dried oregano, and smoked paprika, sautéing for 2 minutes until the spices are fragrant.
Remove the roasted vegetables from the oven and fold them into the skillet with the chicken, tossing well to combine.
Divide the mixture into meal prep containers and allow to cool slightly before refrigerating for a ready-to-eat lunch.
