Cut onion into slivers & slice peppers.

In a separate bowl, combine 1 tablespoon olive oil, juice of ½ lime, chili powder, paprika, onion powder, pepper, cumin and salt. Cut chicken into strips and toss with the spice mixture.

Preheat 1 tablespoon olive oil over medium high. Add ½ of the chicken and cook until just cooked, about 3-5 minutes. Remove from pan and set aside. Repeat with remaining chicken.

Set chicken aside and add 1 tablespoon oil to the pan. Drain onions well (if soaking per note below) and cook 2 minutes. Add in sliced peppers and cook an additional 2 minutes or just until hot. Add chicken back to the pan and stir to combine.

Squeeze additional lime overtop and serve over tortillas.
