To cook the chicken breasts, heat a skillet over medium heat.
Cut chicken to strips and flatten them to an even thickness by cutting them lengthwise and/or pounding them with a mallet. Season with salt and black pepper on both sides.
Thinly slice 1 small onion and 1-2 cloves of garlic.
Lightly oil the skillet with 2-3 tablespoons extra virgin olive oil. Place chicken in the skillet, scatter the onion and garlic around it. Cook it to brown color – see photo. Turn to other side, and cook until browned.
Remove from skillet. Let rest 5 minutes before slicing.
Warm the tortilla according to reheating instructions on the package.
Place all ingredients on the warmed tortilla. (The one in the photo is too crowded. Don’t put so much stuff or it will all fall out of the wrap at the first bite. It’ll be messy. Don’t say I didn’t warn you. But it is good messy. Anyway, so much filling here was only for the purpose of taking the photo). Fold wrap and enjoy.
