Instructions
Heat olive oil in a 12-inch (30cm) non-stick skillet over medium-high heat until the oil shimmers.
2 tablespoons olive oil
Add the chopped onion and cook, stirring occasionally, for 3-4 minutes until softened and translucent.
1 small onion
Add the sliced chicken breasts to the skillet in a single layer, working in batches if needed to avoid crowding the pan.
2 pounds boneless skinless chicken breasts
After 1 minute, add the finely chopped garlic and stir to distribute it evenly among the chicken.
3 cloves garlic
Cook the chicken for 5-6 minutes total, stirring regularly, until golden brown on all sides and the internal temperature reaches 165°F / 74°C.

Reduce heat to low, then pour in the balsamic vinegar. It will bubble immediately — use a wooden spoon or spatula to scrape up any browned bits from the bottom of the skillet.
¼ cup balsamic vinegar
Stir for 1 minute, allowing the vinegar to reduce slightly and thicken into a light glaze that coats the chicken.
¼ cup balsamic vinegar
Remove the skillet from heat, then add the honey and spicy mustard.
1 tablespoon honey, 1 tablespoon spicy mustard
Toss everything together until the chicken is evenly coated in the glossy balsamic glaze.
Season with salt and pepper to taste.
½ teaspoon kosher salt, ¼ teaspoon freshly ground black pepper
Arrange the chopped romaine lettuce in a large salad bowl. Top with the warm glazed chicken, halved tomatoes, and toasted walnuts.
1 large head romaine lettuce, 1 cup cherry or grape tomatoes, ¼ cup walnuts
Freshly grate parmesan cheese over the top and serve immediately while the chicken is still warm.
¼ cup parmesan cheese
Notes
Storage: Transfer the cooked chicken mixture (without greens) to an airtight container and refrigerate for up to 3 days. Keep romaine, tomatoes, and parmesan separate until serving.Freezing: The glazed chicken freezes well for up to 2 months. Thaw overnight in the fridge and reheat gently in a skillet with a splash of water.Make-Ahead: Cook and glaze the chicken up to 24 hours ahead. Reheat in a small skillet over low heat with 1-2 tablespoons of water to loosen the glaze before assembling.Substitution: Boneless skinless chicken thighs work well — slice the same way and add 1-2 minutes of extra cook time.Pro Tip: Add the balsamic vinegar while the heat is still on low and let it reduce for a full minute before adding honey and mustard — this thickens the glaze so it clings to the chicken instead of pooling at the bottom of the bowl.
