Start by cutting the chicken breasts into bite-sized pieces, approximately 1 inch in size.
In a mixing bowl, combine olive oil, minced garlic, lemon zest, and lemon juice. Add salt, black pepper, and dried oregano. Whisk until well combined to create a marinade.
Add the chicken pieces to the marinade and toss to coat evenly. Allow the chicken to marinate for at least 15 minutes at room temperature or refrigerate for up to 2 hours for more flavor.
Heat a skillet or frying pan over medium-high heat. Once hot, add the marinated chicken pieces, making sure not to overcrowd the pan. Cook in batches if necessary.
Sauté the chicken for about 4-5 minutes, turning occasionally, until golden brown and cooked through. The internal temperature should reach 165°F (75°C).
Transfer the cooked chicken bites to a serving dish and garnish with fresh parsley before serving.
Serve these chicken bites with a side of rice, quinoa, or a fresh salad for a complete meal.
Consider adding red pepper flakes to the marinade for a kick of heat.
Store any leftovers in an airtight container in the refrigerator for up to 3 days and reheat before serving.
