Pat the chicken breast dry with a paper towel and season both sides with half of the sea salt, black pepper, and garlic powder.
Rinse and drain the chickpeas, then pat them thoroughly dry with a clean kitchen towel to ensure they achieve maximum crunch.
Heat the extra virgin olive oil in a large non-stick skillet over medium-high heat.
Place the chicken in the skillet and cook for 5-6 minutes per side until golden brown and the internal temperature reaches 165°F, then remove to a plate to rest.
In the same skillet, add the chickpeas and cook for 8-10 minutes, stirring occasionally, until the skins are blistered and crispy.
Turn off the heat and stir the lemon zest, lemon juice, dried oregano, and the remaining salt and pepper into the chickpeas to coat.
Slice the rested chicken breast and serve it over a bed of fresh baby spinach, topped with the warm, zesty chickpeas.
