This is a great side dish - especially for summer. It's easy to make and actually very good for you. Cucumbers are very good for the liver and for your gallbladder. The cucumbers get nice and cold so it's perfect for the summer.
Peel and cut four cucumbers (yes, you want to peel all that nasty waxy skin off the cucumbers)
Thinly slice half of a small red onion.
Pour apple cider vinegar over the cukes. About half a cup.
1 Tbsp sugar (I know....just do it! it cuts out the bitterness and makes it sweet)
Stir it all together and store in the fridge until you are ready to eat it.
