Prep: Wash and dry the strawberries and grapes.
Slice: peel a banana and evenly slice the banana into roughly 1/4" thick pieces.
Trim: take the strawberries and even cut off the stem and the tip.
Tread: using a wooden toothpick, stick the grape onto one end pushing the toothpick roughly halfway through. Then tread on the banana slice and the strawberry. There should be enough of the toothpick for the marshmallow. If not, gently push the fruit further down the toothpick. Next, add the marshmallow to the top of the strawberry. The toothpick should not be sticking out of the top.
Repeat: Place finished Grinch Kabob on a plate and repeat until you have used up all of your ingredients.
Eat: serve by themselves or with a fun yogurt or chocolate dip.
