You can substitute other vegetables in the filling, but be sure to keep the total volume of veggies the same as given here. See the blog post for suggestions.
See the photo in the blog post for an idea of how to roll the spring rolls.
You can freeze the wrapped, uncooked rolls if you like, and fry them straight out of the freezer. Just cook them for a minute or so longer than prescribed here.
You can reheat cooked rolls in the oven – preheat the oven to 350F and reheat them on a baking sheet for 8-12 minutes until crispy. If reheating in the air-fryer, preheat to 300F and air-fry for 10-12 minutes until crispy.
Feel free to use any dipping sauce you like, or skip the dipping sauce altogether.
