Start by slicing the bell pepper and onion into thin strips. For the chicken, cut it into thin strips to ensure even cooking.

In a bowl, combine the chicken, olive oil, fajita seasoning, salt, and pepper. Toss everything together until the chicken is evenly coated.

Turn on your Blackstone griddle and preheat it to medium-high heat for about 5 minutes.

Spread the seasoned chicken strips onto the griddle and let them cook for about 5-7 minutes, occasionally stirring to ensure they cook evenly.

Once the chicken is almost cooked through, add the sliced bell peppers and onions to the griddle. Cook everything together for an additional 5-7 minutes until the veggies are tender and the chicken is thoroughly cooked.

While the chicken and veggies are cooking, warm the flour tortillas on the griddle for about 30 seconds on each side.

Once everything is cooked, assemble your fajitas by placing the chicken and veggie mixture on a tortilla and topping with your favorite toppings. Roll it up and enjoy!
