Actually part of one of my fairly regular steamer cooked meals and a great one for that. Everything can be stacked into the steamer then just left to cook.
The only thing the food needs to finish is some sauce and here I vary things. Sometimes it will be curry, others sweet n sour and bolognese is good too.
I also vary the vegetables in order to make the dish more visually appealing. Cauliflower is a great vegetable but very bland in appearance especially alongside fish and potatoes of a similar colour.
Add in some carrots for the colour though and you have improved the eye appeal of the meal.
I can be creative when cooking but I do often find that I resort to making variations on a handful of basic recipes of which this is one.
Use the basic idea of fish and potato then add a selection of vegetables plus a sauce of choice to get a great meal.
Check out this slightly different but very similar Fish Dinner that I did earlier.
