I’m just going to give you a bunch of ideas for this salad. Depending on what’s availible in your area and how many your making this for choose what you’d like!
Grapefruit (go for pink), Polmelo, Oranges, Tangerines, Mandarins, Blood Oranges (they add amazing color!)
Try to choose a variety of colors to make it visually appealing, and a balance of sour and sweet.
High quality oil such as olive or walnut
Meyer lemon, if unavailable use a less regular lemon
Fresh basil thinly sliced
combine well and pour over the citrus slices.
