In a large mixing bowl, combine Greek yogurt with honey and vanilla extract.
Add diced strawberries, blueberries, or your favorite mix-ins.
Using a spatula or fork, mix Greek yogurt until smoothly combined.
Taste and adjust with more honey, if necessary.
Transfer the Greek yogurt mixture to a loaf pan or dish lined with parchment paper. Using a spatula or spoon, smooth it out evenly.
Top with sliced strawberries or your favorite toppings.
Cover the pan with a piece of parchment paper or plastic wrap to prevent freezer burns. Freeze for 2 hours, then remove from the freezer and let it on the counter for 10 minutes.
Use a sharp knife to slice into even bars. Wrap each piece individually with parchment paper, then place in zipper bags.
Freeze yogurt bars for up to 3 months. Before serving, remove the desired amount from the freezer and let thaw for 5 minutes at room temperature.
