Preheat your oven to 400°F.
Season the chicken breast with salt, pepper, chopped rosemary, and thyme. Drizzle with a little olive oil.
Place the chicken on a baking sheet and roast for 20-25 minutes until cooked through and juices run clear.
While the chicken is roasting, chop the cherry tomatoes and cucumber. Rinse the baby spinach and crumble the feta cheese.
In a small bowl, whisk together the lemon juice, olive oil, a pinch of salt, and pepper to create the dressing.
Once the chicken is done, let it rest for 5 minutes before slicing it into strips.
Assemble the bowl by layering baby spinach, cherry tomatoes, cucumber, and sliced chicken. Top with crumbled feta and drizzle with the lemon dressing.
Serve immediately and enjoy your vibrant, fresh Mediterranean bowl.
