When it comes to cooking sometimes, we are looking for that quick, tasty meal to prepare and have time for other things. Stews are quite versatile and combines well with other dishes.
I always recommend that you have previously ground and boiled tomatoes and pepper in the freezer for when you need to fix something quick like this Mackerel fish stew.
Using smoked fish which technically is already cooked makes life so easy. You do not have to bother with steaming or frying the fish before cooking.
