From time to time eating a salad is a delicious change from your regular lunch sandwich or dinner.
You can of course buy a salad at a supermarket...
...but that certainly won't be a low-carb and/or healthy lunch or dinner salads. Especially if you have type 2 diabetes.
None of the salads in the supermarket are really low in carbohydrates due to the additives in them and - if you do find one - then unfortunately they tend to be not tasty at all.
In addition, they are also very expensive.
In summary: not tasty, expensive and unhealthy.
That is why we have a delicious low-carb salad for you with a delicious mayo-mustard dressing.
