Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Pat the chickpeas thoroughly dry with a paper towel to ensure they achieve a crispy texture during roasting.
Place the diced chicken breast, dried chickpeas, chopped bell peppers, and sliced zucchini onto the prepared baking sheet.
Drizzle the olive oil over the ingredients and sprinkle evenly with smoked paprika, garlic powder, sea salt, and black pepper.
Toss everything together until well-coated, then spread into a single, even layer to ensure uniform cooking.
Roast for 20 to 25 minutes, tossing the mixture halfway through, until the chicken is fully cooked and the chickpeas are golden-brown.
Remove from the oven and immediately drizzle with fresh lemon juice and garnish with chopped parsley before serving.
