The Ingredients

Chicken Breast: Chicken breast is a lean source of protein that helps keep you feeling full and satisfied. It’s low in fat while providing important nutrients like B vitamins, selenium, and phosphorus.

The high protein content makes this recipe a great option for a healthy, filling meal.

Bell Peppers: Bell peppers add natural sweetness, color, and crunch while being low in calories. They are packed with vitamin C, which supports a healthy immune system, and they also provide antioxidants that help protect your cells.

Using a variety of colors gives you a wider range of nutrients.

Onion: Onions add tons of flavor without adding many calories. They contain antioxidants and sulfur compounds that may support heart health and help reduce inflammation.

They also provide a small amount of fiber to help keep you satisfied.

Olive Oil: A small amount of olive oil helps keep the chicken moist and allows the seasonings to coat the ingredients evenly. Olive oil contains heart-healthy monounsaturated fats and antioxidants.

Since only a tablespoon is used for the entire recipe, it adds flavor without adding excessive calories or points.

Fresh Lime Juice: Lime juice brightens up the flavors of the fajita seasoning and adds acidity without extra calories. It’s also a good source of vitamin C and helps enhance the taste of the vegetables and chicken.

Homemade Fajita Seasoning: The homemade blend of chili powder, smoked paprika, cumin, garlic powder, onion powder, black pepper, and cayenne adds bold flavor without relying on high-calorie sauces or seasoning packets that can be higher in sodium.

These spices also provide antioxidants and beneficial plant compounds while keeping the recipe light and flavorful.

How to Make Chicken Fajita Foil Packets

Preheat oven to 425 degrees F or prepare grill for medium-high heat.

Tear off four large sheets of heavy-duty aluminum foil.

In a large bowl, combine chicken, peppers, and onions.

Add olive oil, lime juice, chili powder, smoked paprika, cumin, garlic powder, onion powder, salt, and pepper. Toss until everything is evenly coated.

Divide the chicken and vegetable mixture evenly among the foil sheets.

Fold foil over the mixture and tightly seal the edges to create packets.

For the oven:

Place foil packets on a baking sheet. Bake for 25-30 minutes, or until the chicken reaches an internal temperature of 165 degrees F.

For the grill:

Place foil packets directly on the grill grates. Grill over medium-high heat for 20-25 minutes, flipping once halfway through. Check that the chicken reaches 165 degrees F before serving.
