It seems like watermelon+feta=salad of 2011!
Eleanor found this recipe in Cooking Light August 2011 edition at the orthodontist and thought it looked good. Well, she didn't find this exact recipe since I read it at the office and committed it to memory. I think this may be close, but I'm not sure. I did search for the exact recipe online and didn't find it, so maybe it will be online once the next issue of this magazine is distributed.
Pasta, cooked...about 1/2 lb
diced watermelon, a couple cups
1 seeded cucumber, chopped
crumbles of feta
juice of one lemon
olive oil whisked in to make a dressing
Mix together and put in refrigerator until all cooled.
