The way I do it these days:

1/2 pkg cherry/grape tomatoes sliced in half
1 cucumber
1/4 c (or more!) sliced red onion
1/4 c (or more!) crumbled feta--I usually buy the block and use a fork to scrape it off... much cheaper

2 T olive oil
2 T lemon juice
1 t dried oregano
1/4 t salt

 Combine vegetables and cheese. Whisk together olive oil, lemon juice, oregano, and salt. Pour over vegetables and toss until coated. Serve immediately.

In the summer time when I have lots of tomatoes and cucumbers from the garden, I make a bunch of the dressing and keep it on hand.  

Serves 4 very generously as a side salad.
