A basic cucumber salad with some onion, tomato and vinegar dressing is always great.

This is my go-to summer salad! Chunks of tomato and cucumber with thin-sliced shallot or red onion, salt and let sit for ~20 minutes to release some liquid, drain and add chopped avocado and your favorite canned bean (I like cannellini), dress with black pepper, olive oil and balsamic vinegar.
