Yes, you can freeze pepperoni pasta salad, but there are a few things to keep in mind. First, make sure it's freshly prepared and hasn't been sitting out for too long. Portion it into freezer-safe containers or bags, removing excess dressing if it's mayo-based. Pop it in the freezer as soon as possible to maintain the best texture. When you're ready to enjoy it, simply thaw it in the fridge overnight, give it a good stir, and it should be good to go. Just remember, some ingredients might change in texture after freezing, so it might not be exactly the same as when it was fresh, but it should still be delicious!
