Everybody needs an emergency go to dish when you find that there is no fresh food in the house and you are hungry as hell. The lack of provisions may be the result of a hectic work life or a frenetic social life. Or, like me you may not have been able to face slogging around the supermarket with a blank look on your face as you desperately seek inspiration for dinner.
This is my go to dish calling for only an onion as its fresh vegetable, and there is always one of those lurking around at the bottom of the fridge- right? Ok, so this isn't going to help toward your five a day but it will fill a hungry tummy in about 10-15 minutes. You can throw in whatever veggies (e.g. frozen peas or spinach) you have or a slice of bacon or ham (real or fake) or some cheese to jazz this up.
In relation to balsamic vinegar, for those of you that are gluten free, from what I have read, if it is good quality vinegar with no other ingredients e.g caramel coloring derived from a gluten source is safe for celiacs and those that cannot tolerate gluten (University Chicago Celiac Disease Center). Check the label before you use but generally most distilled vinegars are safe, apart from malt vinegar which is not gluten free.
