To make the citrus dressing, bring water and sugar to a boil over medium-high heat, stirring constantly.
Once water begins to boil, immediately reduce heat to low, and pour in orange juice and lemon juice. Allow to simmer for a couple of minutes, then transfer citrus dressing to the refrigerator to cool.
While your citrus dressing is cooling in the refrigerator, peel and separate tangerines, core and cut your pears, and core and cut your apples.
Add tangerines, pears, and apples to medium bowl, and pour citrus dressing over fruit. Stir with wooden spoon, then cover with plastic wrap and place in refrigerator for 2+ hours so flavors can marinate together.
When ready to serve, remove fruit salad from refrigerator, add sliced banana and mini marshmallows, gently stir again, and ENJOY!
