I think we've had this topic before, but can't find it.
What's your favourite (easy) summer salad?
Mine is sweet corn with red onion and red pepper. Or tomato.
Make a dressing with oil, vinegar, mustard and honey and mix in.
I think the ingredients of the dressing are important - I like walnut oil. And maybe lemon juice instead of vinegar.
I've got another 'keen'... Ouch!
