Preheat an oven to 250°F and line a baking tray with parchment paper.

Next, cut the boneless chicken thighs into medium cubes then set aside.

Combine extra virgin olive oil with lemon juice, minced garlic, oregano, and black pepper then mix well.

Rub the boneless chicken thighs with the spice mixture then spread on the prepared baking tray.

Sprinkle asparagus over the chicken then arrange sliced lemon on top.

Bake the chicken for approximately 25 minutes or until the chicken is cooked through.

Remove the cooked chicken from the oven and transfer to a serving dish.

Serve and enjoy.
