In a mixing bowl, combine the chicken breast pieces with olive oil, minced garlic cloves, lemon juice, salt, black pepper, and the spice mix (paprika, cumin, oregano). Ensure the chicken is well-coated with the marinade. Allow it to marinate for at least 30 minutes.

Chop the Vegetables

While the chicken is marinating, chop the cherry tomatoes in half, dice the cucumber, and finely slice the red onion. Set aside in a bowl.

Cooking

Cook the Chicken

Heat a grill or skillet over medium-high heat. Once hot, add the marinated chicken and cook for about 6-7 minutes on each side, or until the chicken is cooked through and has a nice golden brown color.

Prepare the Garnish

Once the chicken is cooked, remove it from the heat and let it rest for a few minutes. While resting, toss the chopped vegetables together in a bowl with a pinch of salt and pepper.

Serving

Plate the Dish

Slice the grilled chicken into strips and arrange it on a serving plate. Top with the vegetable garnish and sprinkle fresh chopped parsley over the top for added flavor and color.

Serve

Serve immediately while warm, optionally with a side of rice or bread.
