Cook the chicken breasts with the salsa either in the oven or in an Instant Pot.
Oven: place chicken in a casserole dish, pour the salsa over the top, cover the dish with foil and bake at 350 for approximately 50-60 minutes or until the chicken reaches at least 165 F. on a meat thermometer.
IP: Place the chicken in the insert and pour the salsa over the top. Press the "Meat" button and set to 30 minutes.
When chicken is done, shred with two forks.
Lay out a warmed tortilla and place the lettuce on it. Then add the mango and the chicken and wrap it up like a burrito.
Cut in half and serve with a little extra salsa for dipping.
