Preheat your oven to 400°F (200°C) and prepare a small baking dish.
Pat the chicken breast dry and rub with 0.5 tbsp of olive oil, sea salt, black pepper, dried oregano, and garlic powder.
Place the chicken in the baking dish, drizzle with lemon juice, and sprinkle the lemon zest over the top.
Bake for 20-25 minutes, or until the internal temperature reaches 165°F, then let it rest for 5 minutes before slicing.
While the chicken rests, spiralize the zucchini into noodles and halve the cherry tomatoes.
Heat the remaining 0.5 tbsp of olive oil in a large skillet over medium heat.
Add the zucchini noodles and cherry tomatoes to the skillet, sautéing for just 2-3 minutes until the noodles are slightly softened but still al dente.
Plate the zucchini noodles and tomatoes, top with the sliced lemon chicken, and garnish with the grated parmesan cheese.
