Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Rinse and thoroughly pat the chickpeas dry with a kitchen towel to ensure they get crispy.
Slice the bell pepper and zucchini into bite-sized pieces.
In a bowl, toss the chickpeas, peppers, and zucchini with half of the olive oil, garlic powder, smoked paprika, salt, and pepper.
Spread the vegetables and chickpeas in a single layer on the baking sheet and roast for 20-25 minutes until the chickpeas are golden and crisp.
While the vegetables roast, season the chicken breast with the remaining spices and pan-sear in the remaining olive oil over medium-high heat for 6-7 minutes per side until cooked through.
Allow the chicken to rest for 5 minutes before slicing it into strips.
Assemble the bowl by layering the roasted vegetables and chickpeas, topping with the sliced chicken, and drizzling with fresh lemon juice.
