This is another dish that stretches the definition of “healthy”, but on the other hand chicken breast is a lot less fatty than pork, plus this dish fills them with vegetables. So this is still fried, but feels much lighter than ton-katsu.
In any case, my attitude is that it isn’t meals that are healthy or unhealthy, it’s diets. Eat sasami-roll-katsu four times a week and you have an unhealthy diet. Eat it once every two or three months and you have a delicious treat to look forward to as part of a healthy diet.
Preparation is quite similar to ton-katsu’s, but with a twist. Rather than just frying a cutlet, you’re making a kind of meat-and-vegetable roll, battering it, and frying the whole thing! It’s almost like a Japanese cordon bleu.
Making sasami-roll-katsu is not really difficult, but it will take time and your kitchen is going to be a big mess at the end. Sometimes, though, it’s worth it!
