Make a vinaigrette by slowly whisking the olive oil into the apple cider vinegar. Add ½ cup of the chopped mint, ginger, honey, and salt and pepper. Set aside.

Place the arugula in a bowl and toss with a little bit of the vinaigrette. Add watermelon, feta cheese, mint, and almonds. Combine. Finish with a drizzle of vinaigrette.
