Fold the chicken breasts in a saucepan.
Add salt and ground black pepper to taste.
Pour in cold water so that the breasts are completely covered.
Cook over medium heat for 10-15 minutes. To check the chicken’s readiness - break apiece. The meat inside should be white without pink streaks. Or use a cooking dipstick. Temperature 165 F indicates its readiness.
Put the breasts on the board and shred them using two forks. Or cut with a knife.
