It's easy because it's pan-fried rather than deep-fried. It's crusty, and great as an appetizer, snack, or packed in bentos.
I had leftover spring roll wrappers and was thinking of a way to make appetizers. Here's my take on cooking a dish with my favorite ingredients: wiener sausages, cheese, and curry.
Even if you don't boil the wiener sausages before wrapping it, it will cook through when pan-frying and become plump. Serve with ketchup if you like.
