Here is a simple to make a cucumber tomato salad that tastes fantastic.
This is even better if you happen to have fresh tomatoes and cucumbers from your garden, because the taste simply can't be beat. Otherwise you'll want to spend a bit more and buy the hothouse tomatoes and cucumbers. Now, if you want to, and if you have one, it would certainly be delicious to add a diced avocado to this! I didn't have one when I took this picture, but perhaps next time.
Cut cucumber and tomato into chunks and combine in bowl. If you have one of these cool citrus squeezers, half the lime and squeeze juice from it. Salt, mix, taste, salt some more.
