Use medium cookie scoop to make ~9 medium sized watermelon balls and set aside. Use melon baller or a small cookie scoop to make ~27 melon balls with the honeydew and set aside.
Mix all dressing ingredients in a small bowl and toss with melon. Marinate for 1 hour or overnight.
Thread each honeydew ball onto a party pick. I used plastic picks that have a ball at the end so that the melon balls don't slide off. (I used Bonny Party Picks) Gather three melon ball picks and stick a watermelon ball on top and place on individual plates as a starter salad. Top with extra dressing, cotija cheese crumbles, limes and Tajin seasoning.
