This recipe was passed down to me from my grandmother. I hope you enjoy it as much as my family and friends have! Add any additional amount of anything, if desired. Make sure to add salt and pepper!
Heat olive oil in a skillet over medium-high heat; saute garlic until fragrant, about 1 minute. Add chicken; cook and stir until chicken is no longer pink in the center, 5 to 7 minutes.
Mix onion, red bell pepper, black beans, and cilantro into chicken; saute until onion is tender, about 5 minutes. Stir salsa into chicken mixture until heated through, 1 to 2 minutes.
Spoon chicken mixture into tortillas and top with Mexican cheese blend.
