Heat 1 tablespoon of olive oil in a large non-stick skillet over medium-high heat until shimmering.
Add 6 ounces of ground chicken to the skillet, using a wooden spoon to break the meat into small crumbles as it browns for about 5-7 minutes.
Incorporate the diced yellow onion and red bell pepper into the pan, sautéing for 3 to 4 minutes until the vegetables begin to soften and the onion becomes translucent.
Add the diced zucchini and minced garlic, continuing to cook for another 3 minutes until the zucchini is tender but still retains a slight crunch.
Sprinkle the sea salt, black pepper, and dried oregano over the mixture, stirring well to ensure the seasoning is distributed evenly.
Pour in the fresh lemon juice and add the lemon zest, tossing the ingredients for 1 minute to allow the flavors to meld and brighten the dish.
Remove the skillet from the heat and garnish with fresh chopped parsley before serving immediately while hot.
