1. Cut the chicken breast into 1-inch pieces and season with the dried oregano, sea salt, and black pepper.
2. Slice the baby potatoes into thin rounds, about 1/8-inch thick, to ensure they cook quickly on the stovetop.
3. Heat the olive oil in a large non-stick skillet over medium heat.
4. Add the sliced potatoes to the skillet in a single layer and cook for 6 minutes, flipping once, until they are golden and tender.
5. Push the potatoes to the side of the pan and add the chicken pieces, sautéing for 5 minutes until browned and cooked through.
6. Add the diced yellow onion, red bell pepper, and zucchini to the pan, stirring frequently for 4 minutes until the vegetables soften.
7. Stir in the minced garlic and cook for 60 seconds until the aroma is released.
8. Pour the lemon juice over the mixture, scraping the bottom of the pan to incorporate all the savory browned bits before serving.
