Combine spices, lime juice, 1 tsp canola oil and a sprinkle of salt in a bowl. Whisk to combine.
Add chicken and toss to coat. Let marinate for 2 hours or overnight.
Heat a skillet over medium high heat. Add 1 tsp canola oil and when hot, add peppers and onions. Cook for 3-5 minutes.
Add chicken and cook until it’s no longer pink in the middle. Mine took about 10 minutes to cook through and my slices were a bit on the thick side.
Heat tortillas and serve chicken, peppers and onions in the skillet. Let guests serve themselves and build their own!
