Breakfast would often be Muesli and or toast. Sometimes it would be Weetabix. All big "no nos" on a Wheat Free Diet.
So the first change I made was to switch to breakfast cereals with corn as the base, such as Cornflakes.
Porridge is also a great breakfast meal because oats are a carbohydrate that is released slowly into the blood stream, making it less likely you will get severe hunger pangs mid-morning. You can add flavor with honey or fruit.
At first I thought lunch would be a problem. We eat our main meal at dinner time in the evenings, so I do not cook at lunchtime. This is why I got into the habit of having sandwiches.
I switched to jacket potatoes, which are so versatile and there's a variety of fillings you can add that are wheat free. Subsequently I discovered rice cakes and hummous.
As my family enjoys pasta, this was the hardest for me. I found wheat free pasta tasteless and so these days I make suaces that can be eaten on their own, perhaps with salad. So the family has the past and I do without. Or sometimes I will subsitute rice.
I have found that wheat free dieting is rather like cooking for a vegetarian. It is easier to do meals that can be adapted rather than make a completely different meal for the "abstainer".
For example, my family loves a pasta dish made with Chicken and Mascapone and Tomato sauce. I add mushrooms to make the sauce more substantial and the family has pasta but I have salad.
We all love gravy with a traditional roast dinner, but I make the gravy with wheat free flour.
