Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Rinse and drain the chickpeas, then pat them thoroughly dry with a paper towel to ensure maximum crispiness.
Cut the chicken breast into 1-inch bite-sized cubes.
In a mixing bowl, toss the chicken pieces and dried chickpeas with olive oil, smoked paprika, garlic powder, sea salt, and black pepper until evenly coated.
Spread the chicken and chickpea mixture in a single layer on the prepared baking sheet.
Bake for 20 to 25 minutes, tossing halfway through, until the chicken is golden and the chickpeas are crispy.
While the protein roasts, slice the cucumber into thin rounds and place the baby spinach in a serving bowl.
In a small ramekin, whisk together the tahini and lemon juice with a splash of water to reach a drizzling consistency.
Top the spinach and cucumber with the warm roasted chicken and chickpea poppers.
Finish the dish by drizzling the lemon-tahini sauce over the top and serve immediately.
