Preheat oven to 400°F and line a large baking sheet with parchment paper.
Pat the chickpeas dry with a paper towel to ensure they roast until crispy.
In a large bowl, toss the diced chicken, chickpeas, bell peppers, and zucchini with olive oil, sea salt, black pepper, smoked paprika, and garlic powder.
Spread the mixture in a single layer on the prepared baking sheet.
Roast for 20-25 minutes, tossing halfway through, until the chicken is cooked through and the chickpeas are golden.
While roasting, lightly sauté the cauliflower rice in a pan over medium heat for 5 minutes until tender.
Divide the cauliflower rice into bowls and top with the roasted chicken and veggie mixture.
Drizzle with fresh lemon juice and garnish with chopped parsley before serving.
