Absolutely delicious! No red onion -- used white instead. For color, might try green onions next time. Made half a batch, left in fridge overnight, and ate the entire batch at one time.
I saw this in a magazine also. I was going to post the recipe also but I found it here. It was such an unusual recipe I had to try it. It is absolutely delicious. The flavors all go together so well. Even my husband loved it and he usually won't even taste things like this. Luckily I beat him to the leftovers for lunch the next day. He was disappointed when it was gone. I have made it weekly since them since we have tons of fresh corn from the garden. The only change I made was to substitute zucchini ( we have tons) for the cucumber. Also several family members hate cucumbers.
I also had this recently at a barbeque and it was excellent! I made my own version and added a little fresh avocado for a creamier texture, which was a nice change, but next time I'll make it exactly as written. Thank you for posting it!
