If you use chicken breast as a pizza ingredient, it is recommended to cook chicken breast before using it, so as to ensure that the chicken is cooked thoroughly and tastes better and avoid food safety problems.

Here are some ways to cook chicken breast:

1. Cooking: Cut the chicken breast into small pieces and cook in boiling water for about 10- 15 minutes. Cooked chicken breast will turn white. You can poke it with a fork to see if it's ripe.

2. Roasting: Cut the chicken breast into thin slices or small pieces, add proper amount of salt, pepper, olive oil and other seasonings, and bake in a preheated oven for about 20-30 minutes.

3. Frying: Cut the chicken breast into thin slices or small pieces, add some seasonings such as salt, pepper and olive oil, and fry in the pot for about 8- 10 minutes.

Cooked chicken breast can be cut into small pieces suitable for pizza size, then placed on pizza and baked in the oven until the pizza is cooked. If you like more tender chicken, you can marinate the chicken breast with some tender meat powder or sauce before cooking.
