Ingredients

1 lb chicken breasts, sliced into cutlets, then into thin strips
2 bell peppers (any color), seeded and thinly sliced
1 large sweet onion, thinly sliced
8 oz mushrooms, thinly sliced
6 tablespoons vegetable oil, divided
1 lemon, halved
Homemade seasoned salt (see notes)
Ground cumin
Smoked paprika (optional)

Toppings:
Sour cream, shredded lettuce, Pico de Gallo, guacamole

Directions

Prepare the chicken:
In a bowl, season the chicken strips with seasoned salt, a pinch of cumin, and smoked paprika (if using). Toss to coat and set aside.
Prepare the vegetables:
Place sliced bell peppers, onions, and mushrooms in a large bowl. Toss with your hands to combine evenly.
Sear the vegetables:
Heat 1½ tablespoons of oil in a large (12-inch or larger) heavy-bottomed skillet over high heat. When the oil begins to smoke, add ⅓ of the vegetables in an even layer.
Season lightly with seasoned salt, a pinch of cumin, and a drizzle of fresh lemon juice (about ½ teaspoon).
Let the vegetables sear undisturbed until caramelized on the bottom, then toss and sauté for 3–4 minutes, until crisp-tender. Adjust heat as needed to prevent burning.
Transfer vegetables to a plate and repeat this process two more times with the remaining vegetables, adding oil each time.
Cook the chicken:
Add the remaining 1½ tablespoons of oil to the skillet. Add the chicken, drizzle with lemon juice, and sauté until cooked through, about 2–3 minutes.
Combine and serve:
Return the seared vegetables to the skillet, toss everything together, and heat through. Serve immediately with your favorite toppings.

Tips

Use high heat: A hot skillet ensures a perfect sear on both the chicken and vegetables.
Don’t overcrowd the pan: Cooking in batches helps the vegetables caramelize instead of steaming.
Slice evenly: Keep chicken and vegetables in similar thicknesses for even cooking.
Fresh lemon juice: Adds brightness and enhances flavor — don’t skip it!

Variations and Substitutions

Protein swap: Substitute chicken with steak, shrimp, or tofu.
Vegetable options: Add zucchini, cherry tomatoes, or corn for extra color and texture.
Spice level: Increase heat with chili powder or cayenne pepper.
Oil options: Use avocado oil or olive oil instead of vegetable oil for a lighter flavor.
