Option 1: Use the possessive pronoun directly:
* My pizza: "Mine"
* Ishaq's pizza: "His"
Option 2: Use a pronoun referencing the pizza itself:
* My pizza: "It" (Example: "I want to eat it.")
* Ishaq's pizza: "It" (Example: "He finished eating it.")
Option 3: Clarify the situation:
* Instead of saying "Ishaq's pizza," you could say "His pizza" or "The pizza Ishaq ordered."
* Instead of saying "My pizza," you could say "The pizza I ordered" or "My pizza is cold."
The best way to use a pronoun will depend on the specific context of your sentence.
