A pasta sauce is a good way to introduce new vegetables into your children's diet. This one has both red cabbage and courgette in it. They are both vegetables that I would struggle to get my children to eat if I served them individually. However, in a baked pasta dish, with plenty of mozzarella on top, they both ate it quickly and even asked for second helpings.
A note on spices: if you introduce gently spicy food to your children when they are quite young, then they will adapt to it better than if you leave it until later. My children now enjoy a pasta sauce that is spiced with about a teaspoon of chilli powder. By all means, if yours don't, leave it out. You could also start with a smaller amount or a different spice, like cumin, which has a pleasant flavour but is less hot.
