I love avocados! I decided to have a go at an avocado & watermelon salad. I ate all the watermelon while watching TV, so I made this. It's pretty simple. I made a bed of Romaine lettuce in a medium salad bowl, cut up an avocado, and half a medium sized tomato. I put that in the bowl along with 3 slices of white onion, cut into quarters. I sprinkled in some chunks of feta cheese, maybe 1/3 cup (?). Then I drizzled it with lime juice & olive oil. It tasted good to me...
