Steps
1. Start by preparing the salad: In a bowl, combine mixed greens, cherry tomatoes, and cucumber. Drizzle with balsamic vinaigrette and toss gently.
2. For the main course, heat olive oil in a skillet over medium heat. Season the chicken breast with thyme, rosemary, salt, and pepper.
3. Sear the chicken for 6-7 minutes on each side, or until golden brown and cooked through. Squeeze lemon juice over the chicken and let it rest for a minute.
4. For the dessert, melt dark chocolate chips and butter together in a microwave or double boiler. Stir in heavy cream, sugar, and vanilla extract until smooth.
5. Pour the chocolate mousse into a serving dish and refrigerate for at least 30 minutes.
6. Serve the salad on a plate, followed by the chicken breast, and finish with a scoop of chocolate mousse topped with whipped cream.
