Baked chicken thighs, marinated with brown sugar and caramelized onions. Broccoli and mushrooms, sprinkled with cheese on the side.
I would highly recommend marinating the chicken thighs (you may use breast) a night before so that the flavors pop out once you bake it. When you make the sauce, be sure to put the onions on low-temperature, otherwise they will get burnt later on when you bake them.
As for the veggies, I seasoned it with olive oil and a little bit of cheddar cheese, baked it it a low temperature since veggies can cook faster than protein.
