In a large bowl combine grape tomatoes, thinly sliced cucumber, kalamata olives, red onion, and dill. In a small bowl whisk together Greek all-purpose seasoning and olive oil. Pour the dressing over top of the salad. Mix well, and let it rest in the refrigerator for 30 minutes.
Before serving top the salad with crumbled feta. Store leftovers in a sealed container for up to 2 days.
Not a fan of feta? Try goat cheese. Swap out the type of olives. The list is endless!
