The humble jacket potato gets a lot a bad press but potatoes are a good source of starchy carbohydrate and vitamins, we just need to be careful what we put on them. Jacket potatoes are also a relatively cheap meal.
The focus should be on the vegetables. For a main meal, aim to have 2 portions of vegetables. Remember we are trying to eat a rainbow so different coloured vegetables are important.
For example 80g grated carrot, 80g chopped tomatoes, 140g canned tuna (or 140g tinned salmon if you are having oily fish) and a tablespoon a mayonnaise on top of your potato. The tomato (or sweetcorn if you want) will add moisture so you don’t need to add extra butter or oil to your potato.
You will be surprised how full you are after eating the topping so judge the amount of potato based on your appetite.
