Pat the chicken breast dry with paper towels and season both sides with sea salt, black pepper, and dried oregano.
Heat the olive oil in a skillet over medium-high heat. Add the chicken and cook for 6-7 minutes per side until the internal temperature reaches 165°F.
While the chicken is cooking, prepare the juice ingredients by washing the cucumber, spinach, green apple, and ginger.
Roughly chop the cucumber and green apple, and peel the fresh ginger.
Pass the cucumber, spinach, green apple, and ginger through a cold-press juicer.
Squeeze the juice from the half lemon into the green juice and stir well.
Slice the cooked chicken breast and serve it on a plate alongside the fresh green juice for a complete, high-protein detox meal.
