Place 1/2 of the banana slices in the bottom of the mason jar.
Layer 1/4 cup of the vanilla greek yogurt, 1/2 cup strawberries, 1/4 cup of vanilla greek yogurt, and then top with the rest of the bananas and strawberries, and finish with the chocolate chips.
Put the lid on and refrigerator for 1-2 days. If you use fresh strawberries you can eat this immediately. Otherwise enjoy after the strawberries have thawed.
